Hello,
I have an application that make photos into a subdirectory called "DesPictures" in Environment.DIRECTORY_DCIM public directory
Another application scan the "DesPictures" directory and delete the photos one by one.
In Android 10 the code is:
dir = new File (Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + "/DesPictures");
File list[] = dir.listFiles();
if (list != null) {
for (int i = 0; i < list.length; i++) {
list.delete(); //WORKS IN Android 10 but DOES NOT WORK IN Android 11
}
}
Can anybody help me, please, in order to delete each list in Android 11? Thank you
The method, Environment.getExternalStoragePublicDirectory, was deprecated in API level 29 for security reasons.
An alternative is Context#getExternalFilesDir(String).

I am developing a PHP app that runs on an XDA2 PocketPC. It is for use by field engineers to book themselves to jobs whilst on-site, and it will update our internal stock system etc.
The need has arisen for signature capture, whereby a signature area is embedded into a web page and when the client signs the screen, it is transferred safely into a database at our offices.
I have looked at various possibilities but they all seem to rely on ASP/VBSCRIPT.
Has anyone ever come across something that will integrate with my PHP web app?
In a nutshell: Signature region in web page, user signs screen,signature data sent to a SQL database back at base.
Any ideas? :shock:
Hi limepickle
The webbrowser in WM2003 is really quite primitive in comparison to it's desktop counterparts these days. For that reason, i really do not think that you will find a way to do this in the browser.
I write software similar to that which you are talking about using .NET and i've considered using web pages once or twice for simpler apps, but signature capture was always the sticking point which I could never think of a way to acheive...
Sorry to disappoint you :roll:

your gonna get stuck with a php version since the pocket IE isnt that great,
perhaps you can find a flash based signature capture and has flash on the pocket pcs?
this is our solution:
i created a custom application to do this for our company,
its developed using the OpenNet Compact Framework.
its a fullscreen signature app and when the rep is ready to upload the signature they click the send button that transfers it to a ASP.NET web service. this then saves the image as Jpeg to a shared folder and also to SQL for archiving,
check out:
http://www.opennetcf.org/CategoryView.aspx?category=Home

this is an example of the code to use in VS.NET with OpenNetCF.

Yes, I think you're right, Flash will probably be the way to go, seeing as everyone seems to to be .NET / ASP crazy!!!!
LOL
PS. thanks Pope and djrm, I do appreciate you trying to help, its just that anything to do with .net vb etc, may as well be Urdu.

Hello all. I need some information on how i can modify an existing apk and add a file to a specified path during installation.
Better...i need that installation creates a file in data/data/com.myprogram.android/myfile where com.myprogram.android is the path of program data. Is that possible???
thx
*bump* - after one year, this is exactly what i also need!
any answer to this? since i modify an existing .apk, changing the java-code is not an option. solution must be pure .apk based / via the manifest
you could do it in a few steps
1) copy the apk to somewhere safe (/mnt/sdcard)
2) uninstall the apk, maybe use PackageManager
3) unzip the apk to a folder, add your changed/new files, zip up the folder again (extension .apk). Use busybox's zip/unzip if you need
4)sign the new apk using this (i tried it it works)
5)install the new+signed apk, maybe use PackageManager

The way I've done this in the past is just store whatever it is you want to add in the res/raw directory of the project, then when the program first runs, copy the raw resource wherever you want it in the tree.
Code:
// Copy the helper app from resources to an executable in our classpath
protected void CopyExtraBin() {
// check if it's already there
File helper = new File("/data/data/com.mypath.myprog/helper_app");
if (helper.exists()) {
// already there, nothing to do.
return;
}
InputStream setdbStream = getResources().openRawResource(R.raw.helper_app);
try {
byte[] bytes = new byte[setdbStream.available()];
DataInputStream dis = new DataInputStream(setdbStream);
dis.readFully(bytes);
FileOutputStream setdbOutStream = new FileOutputStream(
"/data/data/com.mypath.myprog/helper_app");
setdbOutStream.write(bytes);
setdbOutStream.close();
// set executable permissions on our helper
Process process = Runtime.getRuntime().exec("sh");
DataOutputStream os = new DataOutputStream(process.getOutputStream());
os.writeBytes("chmod 755 /data/data/com.mypath.myprog/helper_app\n");
os.writeBytes("exit\n");
os.flush();
} catch (Exception e) {
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
return;
}
}

Yeah I have the same question. I'm wanting to add some files to /data/data/<appdirectory>/lib but since it's permissions are set to drwxr-xr-x system system I can't write to it without changing apk itself.
I tried putting this into some code and I just alot of cannot find symbol errors and DataInputStream and Toast. I'm sure It's just my limited knowledge and maybe changes in android but this example code doesn't seem to work for me.

Hi, this is my code, i cant get upload a simple file:
Signgin in to DropBox:
.....private AccessTokenPair tokensDB;
.....private DropboxAPI<AndroidAuthSession> mDBApi;
.....final static private AccessType ACCESS_TYPE = AccessType.DROPBOX;
.....AppKeyPair appKeys = new AppKeyPair(APP_KEY, APP_SECRET);
.....AndroidAuthSession sesDropBox = new AndroidAuthSession(appKeys, ACCESS_TYPE);
.....mDBApi = new DropboxAPI<AndroidAuthSession>(sesDropBox);
.....mDBApi.getSession().startAuthentication(this);
When activity resums this code is executed:
.....mDBApi.getSession().finishAuthentication();
.....tokensDB = mDBApi.getSession().getAccessTokenPair();
when the user clicks over a button in same activity next code is executed:
protected void subeArchivos() {
.....// Uploading content.
.....String fileContents = "Hello World, this is only an example!!";
.....ByteArrayInputStream inputStream = new ByteArrayInputStream(fileContents.getBytes());
.....try {
..........mDBApi.putFile("/testing.txt", inputStream, fileContents.length(), null, null);
..........//Log.i("DbExampleLog", "The uploaded file's rev is: " + newEntry.rev);
.....} catch (DropboxUnlinkedException e) {
..........// User has unlinked, ask them to link again here.
..........Log.e("DbExampleLog", "User has unlinked.");
.....} catch (DropboxException e) {
..........toast = Toast.makeText(getApplicationContext(), "C U A: " + e.getMessage(), Toast.LENGTH_SHORT);
..........toast.show();
..........//Log.e("DbExampleLog", "Something went wrong while uploading.");
.....}
}
The code in red throws error. and after the conde in yellow is executed.
My mnifiest permissions are:
.....<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
.....<uses-permission android:name="android.permission.INTERNET"></uses-permission>
.....<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"></uses-permission>
P.D. All works, exept code in red!!
I hope you can help me!! thx!!
anyone??
I didn't understand anything exc. that you can't upload any file with Dropbox, but I had similar problem. Seems you shouldn't delete the Downloads app, else it bugs DB uploads.
Hope it helps.
thx man, every folder in his place, but maybe something in my code is wrong!!
Hi guys, I hope you can help me!
I have a Samsung i-9000 and i'm writing an application to enter the pin code of the SIM card if it has not already been done before.
I inserted android:sharedUserId="android.uid.system" in AndroidManifest.xml and this is the code in my Activity class:
Code:
TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
try {
clazz = Class.forName(tm.getClass().getName());
m = clazz.getDeclaredMethod("getITelephony");
m.setAccessible(true);
it = (ITelephony)m.invoke(tm);
} catch(ClassNotFoundException e) {
Log.e("ClassNotFoundException", e.getMessage());
} catch(ClassCastException e) {
Log.e("ClassCastException", e.getMessage());
} catch(NoSuchMethodException e) {
Log.e("NoSuchMethodException", e.getMessage());
} catch(InvocationTargetException e) {
Log.e("InvocationTargetException", e.getMessage());
} catch(IllegalAccessException e) {
Log.e("IllegalAccessException", e.getMessage());
}
it.supplyPin(pin);
Now I know I have to sign my app with system certificate (or system key) to work with Android 2.3.3, but I don't how I can do it. I never signed an app before, especially as system app.
On google I found this for a Dream telephone:
- In the AndroidManifest.xml of your application: under the <manifest>
element add the attribute android:sharedUserId="android.uid.system".
- Export an unsigned version of your Android application using
Eclipse: right-click on the project >> Android Tools >> Export
Unsigned Application Package.
- Use <root-of-android-source-tree>/out/host/<your-host>/framework/
signapk.jar to sign your app using platform.x509.pem and platform.pk8
in <root-of-android-source-tree>/build/target/product/security
generated earlier: java -jar signapk.jar platform.x509.pem
platform.pk8 YourApp-unsigned.apk YourApp-signed.apk.
I don't understand the meaning of the last point!!!! What have I to do step by step?? Where is <root-of-android-source-tree>/out/host/<your-host>/framework/
signapk.jar file?? Where are platform.x509.pem and platform.pk8? It says "<root-of-android-source-tree>/build/target/product/security", but where is this path?
The setps above are for a Dream telephone, maybe there is something different in Samsung i9000?
I don't know if it could be useful, hower I have a rooted Samsung i-9000 with Darky 10.2 ROM, development tool: Eclipse, OS: Windows7 32bit
Thank you very much!!!!
There is a Dream system certificate made available by the manufacture somehow. Not all manufactures will make available of their system certificate. I too would like to make a system app myself. However, without having the apk signed by the handset system certificate, there is no way obtain system permissions. I was wondering if there is a way to add my own system certificate to my handset given that I have root access to the handset.
Hello
I am working on trying to port halo to cm11 and facing issues.
The Problem:
Its actually giving me nullpointerexception (Heres complete log-> http://pastebin.com/hQ7Wmane ) in BaseStatusBar.java (here's the complete code: http://pastebin.com/bvRaw4ta) in method "mUpdateHalo":
Code:
protected void updateHalo() {
mHaloActive = Settings.System.getInt(mContext.getContentResolver(),
Settings.System.HALO_ACTIVE, 0) == 1;
Resources resources = mContext.getResources();
//I think Next part is where error occurs
if (mHaloActive) {
mHaloButton.setImageDrawable(resources.getDrawable(R.drawable.ic_notify_halo_pressed));
}
else{
mHaloButton.setImageDrawable(resources.getDrawable(R.drawable.ic_notify_halo_normal));}
if (mHaloActive) {
if (mHalo == null) {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mHalo = (Halo) inflater.inflate(R.layout.halo_trigger, null);
mHalo.setLayerType(View.LAYER_TYPE_HARDWARE, null);
WindowManager.LayoutParams params = mHalo.getWMParams();
mWindowManager.addView(mHalo, params);
mHalo.setStatusBar(this);
}
} else {
if (mHalo != null) {
mHalo.cleanUp();
mWindowManager.removeView(mHalo);
mHalo = null;
}
}
}
Possible Cause:
As far as I think, its due to the reason that for some reason its not able to find "ic_notify_halo_pressed" and "ic_notify_halo_normal" resources in drawable. I use xhdpi phone (nexus 4), and these resources are present in drawable-xhdpi folder. So maybe I am wrong.....
Additional Info:
I cherry-picked from these repos->
https://github.com/jabzaVR/aospa_pa...mmit/968104f9aa7ecd0efca153a30cc74464bd0956cf
and https://github.com/jabzaVR/aospa_frameworks_base/commit/ab72e4ab36778474593ffce89150aece01d5f9c6
Since the repo is aospa based, I had to manually patch some files (out of which BaseStatuBar.java aka the file where problem occurs is one file that I had to manually patch).
All other things I think work as ROM builds fine and even starts but causes systemui crash with above given log. Would appreciate any help. If you need some other file, please do tell.
EDIT: Solved the Problem.
How's the progress on this?
