Try to make my app tapping on right places on some apps. I use Runtime.getRuntime().exec() with "input tap x y" adb shell command, but it working only on my activity. What can i do to make it work?
Thread r;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button BtnStart = (Button) findViewById(R.id.btnStart);
try {
Runtime.getRuntime().exec("su");
} catch (IOException e) {
e.printStackTrace();
}
r = new Thread() {
#Override
public void run() {
try{
synchronized (this){
sleep(10000);
}
} catch (InterruptedException e){
}
try {
Runtime.getRuntime().exec("input tap 120 1050");
} catch (IOException e) {
e.printStackTrace();
}
}
};
View.OnClickListener StartClick = new View.OnClickListener(){
#Override
public void onClick(View v) {
StartApp("some.app.here");
r.start();
}
};
BtnStart.setOnClickListener(StartClick);
}
public void StartApp(String AppName){
Intent LaunchApp = getPackageManager().getLaunchIntentForPackage(AppName);
if (LaunchApp != null) {
startActivity(LaunchApp);
}
}
Find a way like:
try {
dataOutputStream.writeBytes(command + "\n");
dataOutputStream.flush();
} catch (IOException e) {
e.printStackTrace();
}
Where "command" some command with "su" preveosly

I write this function to get video time . This functions works fine but when I backpress then it throws exception .
public void videoTimer ()
{
try

running = true;
final int duration = mVideoView.getDuration();
thread = new Thread(new Runnable()
{
public void run()
{
do
{
tvVideoTimer.post(new Runnable()
{
public void run()
{
int time = (duration - mVideoView.getCurrentPosition()) / 1000;
tvVideoTimer.setText(getTimeString(mVideoView.getCurrentPosition()));
}
});
try
{
Thread.sleep(500);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
if (!running) break;
}
while (mVideoView.getCurrentPosition() <= duration);
}
});
thread.start();

Can any one help me with this?
Printers have predefined character sets built in. These character sets are known as code pages.
Your Bluetooth printer, like most POS printers doesn't seem to support Unicode.
To solve this you could try converting your output to an image and send it to the printer as bytes using an emulation the printer understands.(PCL, ESC/POS, ZPL etc.)
My app breaks down when I attempt to record a second a time when I hit the stop button. I went through this code several times. I can't find the problem. I'm not sure if its my MediaRecorder or my MediaPlayer. It works the first time around. But not the second time. can anyone find the problem.

I figured out the issue. In the beginRecording method, I have an if and else statement that handles the output file. Unfortunately, the code that I had in the else statement was something that I wanted to always run no matter what.
Hi there I have built a soundboard for a character of mine called Aussie Bloke - the soundboard contains 30 buttons and 30 mediaplayers. I originally used one mediaplayer for all buttons but eventually the sounds would stop playing after about 20 random presses. So I decided on using seperate mediaplayer objects for each sound as used in the original soundboard template I used. This worked fine you could press buttons all day and get sounds working properly ..but the problem I have is that when the activity is sent to the background and brought back again even after a few seconds the app crashes when you press a button..I tried creating an onResume method to prepare all the players but this just made the app crash right from the start..sorry I am very new to coding and app building so there may be an obvious solution I have overlooked or been completely unaware of.

You need to implement onResume() method in your activity and recreate there your mediaplayer objects:
public void onResume() {
super.onResume();
// ...
beer1 = MediaPlayer.create(this, R.raw.beer1);
beer2 = MediaPlayer.create(this, R.raw.beer2);
beer3 = MediaPlayer.create(this, R.raw.beer3);
// ...
}

At first, my android device scans for bluetooth devices and then displays them in a listview. I select one of them and a new screen appears. How to return to the main screen when the connection is lost. Following is the code for selected device screen.
public class devicefound extends Activity implements OnClickListener {
private BluetoothAdapter mBluetoothAdapter = null;
private BluetoothSocket btSocket = null;
private OutputStream outStream = null;
Button b1;
private static final UUID MY_UUID =
UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
public static String address;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
findViewById(R.id.b1).setOnClickListener(this);
b1 = (Button) findViewById(R.id.b1);
}
#Override
public void onStart() {
super.onStart();
String address = getIntent().getStringExtra("address");
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
try {
btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) { }
run();
}
public void run(){
try {
btSocket.connect();
} catch (IOException e) {
try {
btSocket.close();
} catch (IOException e2) { }
return;
}
}
public void onClick(View v){
String message1 = "1";
byte[] msgBuffer1 = message1.getBytes();
try{
outStream = btSocket.getOutputStream();
} catch (IOException e){ }
try {
outStream.write(msgBuffer1);
} catch (IOException e) {
}
}
}
#Override
public void onPause() {
super.onPause();
if (outStream != null) {
try {
outStream.flush();
} catch (IOException e) { }
}
}
#Override
public void onStop() {
super.onStop();
}
#Override
public void onDestroy() {
super.onDestroy();
}
}
As I know you should use BroadcastReceiver in a such situation.
Something like this http://android-er.blogspot.com/2011/05/start-bluetooth-discoverable-and.html
If you want to return to the previous screen, then you can call the finish method which your devicefound class inherits from Activity.
