Hello,
Recently I started working on bluetooth chat app for my final year project. I took the example coding available in the sample app in Eclipse and trying to improve it. Now I'm trying to insert 2 new functions into it, 1 - the upload button for uploading any files, 2 - bubble chat interface.
I am a beginner at android programming. I tried exploring draw 9 patch for the bubble patch. Somehow I get the bubble chat done, but not perfectly. I can make it send & receive with the same bubble style. What I'm trying to do is, receive message will show in Green bubble while send message will show Yellow Bubble. I tried the getView() method but didn't understand any of it.
As for the upload button, I'm having problem at the uploading part. I get the selecting the file part done, but I don't know how to make it automatically send the file after it being selected. I tried Googling and most of the result show Image upload. Thanks for those image upload tutorial, I get as far as choosing the file. As for uploading it(sending the file to the other paired device), I'm completely clueless...
The part that I'm having problem I highlight it with red color.
Here's my coding(technically it isn't my coding, it the sample coding with minor modification):

I'm not sure how to code for arduino. But the part how to access through a button click, i have an idea about that.
you can just open a sample bluetooth chat in eclipse, but instead of set the page auto open. just create a new main page, and add a button then, just "hyperlink" it to the bluetoothchat.
to navigate between pages using a button, i'm sure there's tons of tutorial available in google or you can just search "cornboyz" in youtube. that the best tutorial i followed back when i'm still doing android programming. I can't help you much in coding. but i know where you're getting at. Its been 2 years, last i explore android programming.
so. sorry

Good day to you all. I have problems with my application, no synchronization with db. An error occurs when you try to log in or register, and the error code indicates a request raw.query.
Code my db.
Code:
CREATE TABLE `logpass` (
`_id` INTEGER PRIMARY KEY AUTOINCREMENT,
`login` TEXT,
`pass` TEXT,
`Name` TEXT,
`Surname` TEXT,
`Groupi` TEXT

And code Main Activity (where to log in)
Code:

e2 = (EditText) findViewById(R.id.pass);
b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

String password = e2.getText().toString();
Boolean Chkloginpass = database.loginpassword(login, password);
if
(Chkloginpass == true) {
Toast.makeText(getApplicationContext(), "Successful log in", Toast.LENGTH_SHORT).show();
b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this,Main3Activity.class);
startActivity(i);
}
});
} else
Toast.makeText(getApplicationContext(), "Inccorect log or pass", Toast.LENGTH_SHORT).show();
}
});
b2 = (Button) findViewById(R.id.register);
b2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v){
Intent i = new Intent(MainActivity.this, LoginLoginActivity.class);
startActivity(i);
}
});
}
}
Also i can send full database
Hello there!
I would need some help reverse engineering an app and recompiling it with some different code afterwards.
The App coordinates all the different components of my phone to work properly.
When you press the two fingerprint sensors, the app gives you haptic feedback and turns the screen from front to back or vice versa, depending on which side is facing up.
I need the app to do exactly that once when i wake up my phone either with fingerprint or power button, so the display illuminates which is facing up, and not the one i used recently.
I have some experience with java, but all i got are the .smali documents.
Is there any way to reliably get smali into java and back?

Hello there!
I would need some help reverse engineering an app and recompiling it with some different code afterwards.
The App coordinates all the different components of my phone to work properly.
When you press the two fingerprint sensors, the app gives you haptic feedback and turns the screen from front to back or vice versa, depending on which side is facing up.
I need the app to do exactly that once when i wake up my phone either with fingerprint or power button, so the display illuminates which is facing up, and not the one i used recently.
I have some experience with java, but all i got are the .smali documents.
Is there any way to reliably get smali into java and back?

Try APKtool, open source, most used out there.
"apktool d (nameof the app).apk"
"apktool b (name of the app).apk" to recompile
If it's a system file, make sure you don't modify the original signature by adding -c to the last command.
Have a good day
