This line of code request permission for capturing screen. Each time my code call that and it show a dialog for permission. But if i click "don't show this again", it won't request permission but grant permission in the background. How can i take permission only once and grant all time without selecting don't show again?? Full code is given here

public void onToggleScreenShare(View view) {
if (((ToggleButton) view).isChecked()) {
if (mMediaProjection == null) {
startActivityForResult(mProjectionManager.createScreenCaptureIntent(), REQUEST_CODE);
} else {
startRecording();
}
} else {
releaseEncoders();
}
}
On this Method startActivityForResult() method prompt screen capturing permission. If grant permission or deny it the code transfer call to onActivityResultMethod()
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG, " requestCode " + requestCode + " resultCode " + requestCode);
if (REQUEST_CODE == requestCode) {
if (resultCode == RESULT_OK) {
mMediaProjection = mProjectionManager.getMediaProjection(resultCode, data);
startRecording(); // defined below
} else {
Log.d(TAG, "Persmission denied");
}
}
}
On this method we get Intent data and resultCode. To further use MediaProjectionManager without requesting continuous permission, we have to save reference of the Intent and value of resultCode and use mediaProjectionManager via this line of code
mMediaProjection = mProjectionManager.getMediaProjection(saveResult, savedIntent);
So it won't request permission again as permission is already granted

Android - Passing long array via broadcast intent

I wrote a little android program, there is a main activity with a broadcast listener, and i create another thread. The thread searches for prime numbers, and loading them into a long arraylist, and after every 3 seconds, sends the filled array to the main activity via broadcast. Everythings ok, until i'm trying to get the long array extra from the intent. It causes every time a nullpointerexception.
I tried with a string arraylist, it worked, but i am curious because the intent has an "getlongarrayextra" method.
Here is my code:
public class MainActivity extends Activity {
public static String BROADCAST_THREAD_KEY = "broadcast_key";
public static String EXTRAARRAYID = "primes";
private static long MAXNUM = 2000000;
private PrimeCalculatorThread thread;
TextView textView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.numberstext);
}
private BroadcastReceiver receiver = new BroadcastReceiver() {
public void onReceive(android.content.Context context,
android.content.Intent intent) {
String origitext = textView.getText().toString();
long[] primes = intent.getExtras().getLongArray(EXTRAARRAYID);
Log.d("ASD", "broadcast received" + primes.toString());
StringBuilder builder = new StringBuilder();
if (primes != null) {
for (long prime : primes) {
builder.append(prime + " - ");
}
textView.setText(origitext + "\n" + builder.toString());
}
};
};
#Override
protected void onResume() {
Log.d("ASD", "ONRESUME");
initReceiverAndStartThread();
super.onResume();
}
private void initReceiverAndStartThread() {
IntentFilter filter = new IntentFilter(BROADCAST_THREAD_KEY);
registerReceiver(receiver, filter);
thread = new PrimeCalculatorThread(getBaseContext(), MAXNUM);
thread.start();
Log.d("ASD", "THREAD STARTED");
}
and the second thread:
public class PrimeCalculatorThread extends Thread {
private Context context;
private long maxnum;
List<Long> primes;
boolean isrunning;
public void setIsrunning(boolean isrunning) {
this.isrunning = isrunning;
}
private long counter = 0;
private long DELAYBETWEENBROADCAST = 3000;
public PrimeCalculatorThread(Context c, long maxnum) {
this.context = c;
this.maxnum = maxnum;
primes = new ArrayList<Long>();
}
#Override
public void run() {
long startTime = System.currentTimeMillis();
long estimatedTime;
isrunning = true;
for (long i = 0; i < maxnum; i++) {
Log.d("ASD", Boolean.toString(isrunning));
if (!isrunning)
break;
Log.d("ASD", i + "");
estimatedTime = System.currentTimeMillis() - startTime;
if (isPrime(i)) {
primes.add(i);
Log.d("ASD", i + "is a prime");
} else {
Log.d("ASD", i + "is not a prime");
}
if (estimatedTime > counter * DELAYBETWEENBROADCAST
+ DELAYBETWEENBROADCAST) { // elapsed another period
Log.d("ASD", primes.toString() + " will be sending.");
sendBroadCast();
primes.clear();
counter++;
}
try { //for debug purposes
Thread.sleep(250);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
private void sendBroadCast() {
Intent intent = new Intent(MainActivity.BROADCAST_THREAD_KEY);
intent.putExtra(MainActivity.EXTRAARRAYID, primes.toArray());
context.sendBroadcast(intent);
Log.d("ASD", "BROADCAST SENT" + primes.toString());
}
boolean isPrime(long n) {
if (n < 2)
return false;
if (n == 2 || n == 3)
return true;
if (n % 2 == 0 || n % 3 == 0)
return false;
long sqrtN = (long) Math.sqrt(n) + 1;
for (long i = 6L; i <= sqrtN; i += 6) {
if (n % (i - 1) == 0 || n % (i + 1) == 0)
return false;
}
return true;
}
}

The problem is that you are managing a list of Long objects and passing it in putExtra, which means you are invoking putExtra(String name, Serializable value). Then you try to get that value using getLongArray(), but you haven't put any long array extra, you see! To solve this, replace
intent.putExtra(MainActivity.EXTRAARRAYID, primes.toArray());
with
long[] primesArray = new long[primes.size()];
for (int i = 0; i < primes.size(); i++) {
primesArray[i] = primes.get(i);
}
intent.putExtra(MainActivity.EXTRAARRAYID, primesArray);
This will invoke the correct putExtra(String name, long[] value) method.

Android mediaplayer volume change issues after phone call

I am using a service in my mp3 player to play media. I use mediaplayer object to play music. Normally the volume keys work when the music is playing. I also used Telephony Manager in my service to check phone calls. And I start and stop the music when the call is disconnected and is in progress respectively. But after the disconnection of phone call, the volume keys stopped working. I can see the dialog of volume change. But the sound volume don't change. Any idea? It is even happening in native player.

What am I missing in this activity that could be causing a memory leak/OOM error?

Here's what it looks like. I'm hoping a visual will help you help me!
I have tested it on three devices and four emulators with various screen sizes (so different image sizes) and versions of Android, and I haven't gotten any out of memory errors. I let my 3-year-old repeatedly pound on the animals and flip through them like crazy and still no OOM.
According to Google Play there are close to 200 installations since September 3rd 2013. I've only gotten one report of an OOM error so far, but now I'm worried that they are going to start rolling in. I'm including the whole activity in case one of my overridden methods has relevant information or something like that. This is my first published app so please excuse any newbie mistakes and feel free to criticize anything (as long as you include some suggestions for correcting it!)

How can i show my battery level in AppWidget?

I want to show the battery level in my AppWidget. I used below code to get battery level in my activity
BroadcastReceiver batteryReceiver = new BroadcastReceiver() {
int scale = -1;
int level = -1;
int voltage = -1;
int temp = -1;
#Override
public void onReceive(Context context, Intent intent) {
level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
temp = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE, -1);
voltage = intent.getIntExtra(BatteryManager.EXTRA_VOLTAGE, -1);
Log.d("Battery_level", ""+level);
}
};
IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
registerReceiver(batteryReceiver, filter);
How can i implement this in my Class which extends AppWidgetProvider?
public class HomeWidget1 extends AppWidgetProvider {
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[]
appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
#Override
public void onReceive(Context context, Intent intent) {
}
What should be the code in onUpdate and onReceive method??

This code gives you the battery level:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.BatteryManager;
import android.os.Bundle;
import android.widget.TextView;
public class AndroidBattery extends Activity {
private TextView batteryLevel, batteryVoltage, batteryTemperature,
batteryTechnology, batteryStatus, batteryHealth;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
batteryLevel = (TextView)findViewById(R.id.batterylevel);
batteryVoltage = (TextView)findViewById(R.id.batteryvoltage);
batteryTemperature = (TextView)findViewById(R.id.batterytemperature);
batteryTechnology = (TextView)findViewById(R.id.batterytechology);
batteryStatus = (TextView)findViewById(R.id.batterystatus);
batteryHealth = (TextView)findViewById(R.id.batteryhealth);
this.registerReceiver(this.myBatteryReceiver,
new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
}
private BroadcastReceiver myBatteryReceiver
= new BroadcastReceiver(){
#Override

batteryStatus.setText("Status: " + strStatus);

}
batteryHealth.setText("Health: " + strHealth);
}
}
};
