Hi.
I was loking the system apps of my LG P769 with firmware v20f and found something interesting.
I think the LGSystemService app is responsable of unlocking the bootloader. I extracted the contents of The app and found a file called libunlock.so, wich oviously is the activity that perform the bootloader unlock.
So my idea is that if we are able to view se source of the app the can understand the bootloader unlock process and even find a better way. But i'm not good with android aps and reverse engineering.
This is a interesting thing what you see if you open the libunlock.so file with a text editor:
/dev/block/platform/omap/omap_hsmmc.1/by-name/nv Can't open NVDATA partition ret = %d
Cannot seek to real block device footer
Can't read unlock bit.
gsm.operator.numeric network connection is not set
00101 Test network is connected
network connection is set operator=%s
lock_state=%x, mnc=%d,mcc=%d
ro.build.target_operator bootloader_unlock_operator_bit_write: unlock_value=0x%04x
----------------------------------------------
boot loader unlock setup process is starting~~!!!
thread create error : return thread 0 %d
Device Unlock is permitted. But, unlock was not applied
Device is already unlocked
Bootloader Unlock is prohibited
Unlock bit is full!!!
Does anyone want to do something?
Look at this:
.bss:0000301C EXPORT value_con

It looks like the app checks the operator (Damn T-Mobile), sim state, etc. Any ideas?
This is the ActivityManifiest.xml file:

The red lines (i think) confirm the bootloader unlock action.

I have a sola, running the JB port from munjeni.
I'm devlopping an app and I get
Failure [INSTALL_FAILED_INVALID_APK] when trying to debug on the phone. USB debug activated of course.
I see this message as well DeviceMonitor: Adb rejected connection to client '21134': closed
My Nexus 7 when i did that, aksed me to autorize my PC. It seem the sola just deny acces ?
Is that some problem with the JB port ? Common problem with the sola ?? Invalid apk, not really a usefull message.
I'm using intelliJ, and here is the manifest, just in case :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.MyLauncher"
android:versionCode="1"

</manifest>
I did some test, put akp on SD, install, start -> all OK.
So apk is valid for sure, and compatible. Had to be some securitty thing bloking it.

Did you solve?
Yes, got myself a nexus 4
Joke aside, look around in the developer setting, at adb and all.
And the max / min sdk version.
You might also want to try adb install name.akp see what happens.
What phone and rom are you using exactly?

Hi I created a test android app that does two simple things, open the browswer and open the calculator
My main problem is that once I put a custom permission inside the mainfest, I can no longer open my own application. The app does appear on the launcher screen but when I launch it, it will say "App isn't installed". However using a second app and giving it the proper uses and making sure it's signed by the same signature it opens fine.
Here is the manifest for my main app:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.dms_test_app2"
android:versionCode="2"
android:versionName="1.1" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<permission
android:name="com.example.test"
androidrotectionLevel="signature" android:label="this is my custom permission" />
<uses-permission android:name="com.example.test"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
androidermission="com.example.test"
android:name="com.example.dms_test_app2.MainActivity"
android:label="@string/app_name"
android:launchMode="singleInstance">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I understand from logcat that the issue is that the LAUNCHER does not have the proper permission:
E/Launcher( 1392): java.lang.SecurityException: Permission Denial: starting Inte
nt { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0
x10200000 cmp=com.example.dms_test_app2/.MainActivity } from ProcessRecord{b5430
118 1392:com.android.launcher/u0a10002} (pid=1392, uid=10002) requires com.examp
le.test
However if you check my manifest, I clearly declared the <uses-permission> tag.
How can I fix this?
Thanks for reading.

Hello all,
i just registered here to find out if opening a KML file on my SD card with Google maps in offline mode can work.
I am looking for an solution quite a time, but only found this thread on stackover...
To load kml into Google Maps on Android without writing an app, you can create a little html file somewhere with a geo-uri link to the kml file and then click on that link in any Android web browser.
For example: suppose your kml file is located in /sdcard/overlay.kml then you write a geo-uri link like this:
<html>
<head><title>Example KML link page using a geo-uri</title></head>
<body>
overlay.kml
</body>
</html>
Click to expand...
Click to collapse
Clicking on the link will launch Maps and then Maps will attempt to load and your kml.
Be warned however that the Android version of Maps does not appear to handle the same version/range of kml elements as the desktop version (or desktop Google Earth).

[Appjolt] Get money from uninstalls
Hello everybody, I just found a system allow you earn money from uninstalls, this is Appjolt, show advertisements when user uninstall your app. Sound’s good, right? I will guide you in detail:
1. Register your account with this link:
https://admin.appjolt.com/Landings/Monetize?rf=6F/+V7zzEdpJM73Iydu0EQ==
You will have 50$ in your account. The minium money to withdraw is 100$. You can use your paypal or bank account.
2. Download SDK in Android SDK or iOs SDK, it has unity plugin for android and ios, just 200kb
3. In Applications, click +Add Application
4. After submited your app, click +Add Campain to creat a campain (4 type):
- Monetize: show advertisements
- Winback: offer the user to re-install your app and win a prize (gem, gold, virtual item or something real)
- Cross Promote: present your another app
- Survey: asking the user why they are uninstalling your app
5. Analyze uninstall: mixpanel, omniata, appsee, coolaData
Example with Mixpanel, you register an Mixpanel account and copy the Token and paste to appjolt
6. Import Appjolt plugin to your unity game
- The first step of the integration is to import the appjolt Unity package. To do so, simply drag and drop Appjolt.unitypackage into the assets folder of your project in the Unity editor, and the following window will come up, Make sure all the resources are selected and press import:
- The next step is to add a GameObject to any scene that will integrated with Appjolt. To do so, create a new GameObject in the root of the scene’s hierarchy and rename it to “Appjolt”. Next, add an existing script component to the new Appjolt GameObject, select the AppjoltUnity.cs
script from your scripts. Your scene editor should then be configured to and look similar to the following screenshot:
Now, whenever you’ll need to call Appjolt in a Unity scene, to access the SDK’s main object, use the following code:
appjoltUnity = GameObject.Find ("Appjolt").GetComponent<AppjoltUnity> ();
That’s it. Your project’s now set up with Appjolt, now all that’s left is to implement specific
features.

Hello there!
I have a problem with my app. I am working on a website and it's associated android app.
If the system sends an email with a link within, I want the app to open to this specific content. The app opens but not where it's supposed to be. It stays on the main page of the app.
The links are supposed to auto connect the user, so he can access the app as he wishes automatically, so my links have this form:
https://www.mysite.com/autoconnect/stringHASH/stringKEY
I don't know in advance what will be put in the hash and key parts. So I don't know what to put in the manifest to make this work.
Here is what I currently have in my manifest file:
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" />
<data android:host="mysite.com" />
<data android:pathPrefix="/autoconnect/" />
</intent-filter>
Did I miss something? I need to add I have generated the well-known file and it is on my server.
Thank you for your help!
