How do I implelment Android 6.0 Runtime Permissions On Existing App

Problem:
I have an existing app that I would like to implement Android 6.0's Runtime Permissions on. I have read a lot of different things on Runtime Permissions, but I just can't seem to wrap my head around all the different snippets. Nothing I have found actually shows how to implement this into an existing Activity.
Other Points
When I run my existing application targeting SDK v23 I get the permission error as expected, but the permission error I get is not even a permission that I am requesting. I have the SEND_SMS permission in the Manifest file, but the error I am getting is for READ_SMS. My app runs fine on pre 6.0 without READ_SMS.
I would like the my app to ask for permission as soon as the app is launched because the sole purpose of the app is the send an SMS message, so without that permission there is no other use for the app.
Questions:
How would I implement Runtime Permissions for SEND_SMS into my existing Activity as soon as the app is launched?
Does the handling of these permission need to run in a background thread?
Do I also need permissions for READ_SMS since that is the permission error that it is giving (even though that permission has never been used on my app)?

The runtime permission model for Android 6.0 is mainly divided into part
1. Checking Permission
2. Requesting Permission
you can create two method for this thing in your activity, As follow
Check Permission
private boolean checkPermission(){
int result = ContextCompat.checkSelfPermission(context, Manifest.permission.READ_SMS);
if (result == PackageManager.PERMISSION_GRANTED){
return true;
} else {
return false;
}
}
Request Permission
private void requestPermission(){
if (ActivityCompat.shouldShowRequestPermissionRationale(activity,Manifest.permission.READ_SMS)){
Toast.makeText(context,"Read Sms Allowed.",Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(activity,new String[]{Manifest.permission.READ_SMS},PERMISSION_REQUEST_CODE);
}
}
Last but not least you need to override the onRequestPermissionsResult method
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Snackbar.make(view,"Permission Granted, Now you can access SMS.",Snackbar.LENGTH_LONG).show();
} else {
Snackbar.make(view,"Permission Denied, You cannot access SMS.",Snackbar.LENGTH_LONG).show();
}
break;
}
}
as you asked do i need to run this in thread .. answer is No Just do this in main thread

If you want to do less code then, please use Dexter is an Android library that simplifies the process of requesting permissions at runtime.

Cannot close turnbased multiplayer match with Google Play Games

I have a problem closing my game after the last player close the last match. My turn scheme is:
Player A
Player B
Player B
Player A
Player A
Player B
The game works well but in turn "6" when player B try to close the match, player A always see the matsh as "my turn" and not as "completed"
here there is the code thar rules turns and game ended:
#Override
public void onGameEnd(final NMXGameData updatedData) {
super.onGameEnd(updatedData);
if (updatedData.getMatchNumber() == NMXGameConfig.MATCHES) {
boolean iWin = updatedData.getResultPoints()[1] > updatedData.getResultPoints()[0];
boolean tile = updatedData.getResultPoints()[1] == updatedData.getResultPoints()[0];
ParticipantResult opponentParticipantResult;
ParticipantResult myParticipantResult;
if (tile) {
opponentParticipantResult = new ParticipantResult(getOpponentId(), ParticipantResult.MATCH_RESULT_TIE, 1);
myParticipantResult = new ParticipantResult(getCurrentPlayerId(), ParticipantResult.MATCH_RESULT_TIE, 1);
} else {
if (iWin) {
opponentParticipantResult = new ParticipantResult(getOpponentId(), ParticipantResult.MATCH_RESULT_LOSS, 2);
myParticipantResult = new ParticipantResult(getCurrentPlayerId(), ParticipantResult.MATCH_RESULT_WIN, 1);
} else {
opponentParticipantResult = new ParticipantResult(getOpponentId(), ParticipantResult.MATCH_RESULT_WIN, 1);
myParticipantResult = new ParticipantResult(getCurrentPlayerId(), ParticipantResult.MATCH_RESULT_LOSS, 2);
}
}
ArrayList<ParticipantResult> participantResultArrayList = new ArrayList<>();
participantResultArrayList.add(opponentParticipantResult);
participantResultArrayList.add(myParticipantResult);
Games.TurnBasedMultiplayer.finishMatch(getApiClient(), match.getMatchId(), new Gson().toJson(updatedData).getBytes(), opponentParticipantResult, myParticipantResult).setResultCallback(new ResultCallback<TurnBasedMultiplayer.UpdateMatchResult>() {
#Override
public void onResult(TurnBasedMultiplayer.UpdateMatchResult updateMatchResult) {
finish();
}
});
} else if (updatedData.getMatchNumber() < NMXGameConfig.MATCHES) {
if (getNextPlayerIndex(updatedData.getMatchNumber()) != getNextPlayerIndex(updatedData.getMatchNumber() - 1)) {
Games.TurnBasedMultiplayer.takeTurn(getApiClient(), match.getMatchId(), new Gson().toJson(updatedData).getBytes(), getNextParticipantId());
} else {
Games.TurnBasedMultiplayer.takeTurn(getApiClient(), match.getMatchId(), new Gson().toJson(updatedData).getBytes(), getCurrentPlayerId());
startActivity(startNewOnlineGameIntent(this, updatedData, match.getMatchId()));
}
finish();
}
}
private String getCurrentPlayerId() {
return match.getParticipantId(Games.Players.getCurrentPlayerId(getApiClient()));
}
private String getOpponentId() {
for (String id : match.getParticipantIds()) {
if (!id.equals(getCurrentPlayerId())) {
return id;
}
}
return null;
}
private int getNextPlayerIndex(int nextRoundIndex) {
nextRoundIndex = nextRoundIndex + 1;
return (nextRoundIndex / 2) % 2;
}

I finally figured it out.
I don't know if that is the desired behavior but when in round 6 player_B calls:
Games.TurnBasedMultiplayer.finishMatch(getApiClient(), match.getMatchId(), new Gson().toJson(updatedData).getBytes(), opponentParticipantResult, myParticipantResult).setResultCallback(new ResultCallback<TurnBasedMultiplayer.UpdateMatchResult>() {
#Override
public void onResult(TurnBasedMultiplayer.UpdateMatchResult updateMatchResult) {
finish();
}
});
The turn goes to player_A that see that match as "my turn". At this point player A must call Games.TurnBasedMultiplayer.finishMatch(getApiClient(), match.getMatchId()) (without playing a real game) and the game is completed for both players

android: why getrotationmatrix return false?

I want to get the orientation of my phone and I have using this code that I find lot of people using it. this is the code
public void onSensorChanged(SensorEvent event) {
//if the data sensor is unreliabel
if(event.accuracy == SensorManager.SENSOR_STATUS_UNRELIABLE)
return;
//gets the value
switch (event.sensor.getType()) {
case Sensor.TYPE_ACCELEROMETER:
gravity = event.values.clone();
break;
case Sensor.TYPE_MAGNETIC_FIELD:
geomag = event.values.clone();
break;
}
getOrientation();
}
private void getOrientation(){
//if gravity n geomag have value, find the rotation matrix
if(gravity != null && geomag != null){
//check the rotation matrix found
boolean success = SensorManager.getRotationMatrix(inR, I, gravity, geomag);
if(success){
SensorManager.getOrientation(inR, orientVals);
azimuth = Math.toDegrees(orientVals[0]);
TextView azi = (TextView) findViewById(R.id.textAzi);
azi.setText("azi : " + azimuth);
}
TextView cek = (TextView) findViewById(R.id.cek);
cek.setText("rotation: "+success);
}
but why the getrotationmatrix always return to false?
where is the problem?

I've try again and get the solution
but I change the code to become like below
public void onSensorChanged(SensorEvent event) {
// TODO Auto-generated method stub
switch (event.sensor.getType()) {
case Sensor.TYPE_ACCELEROMETER:
for(int i=0; i<3; i++){
accelValues[i] = event.values[i];
}
if(compassValues[0] != 0)
ready = true;
break;
case Sensor.TYPE_MAGNETIC_FIELD:
for(int i=0; i<3; i++){
compassValues[i] = event.values[i];
}
if(accelValues[2] != 0)
ready = true;
break;
}
if(!ready)
return;
boolean cek = SensorManager.getRotationMatrix(inR, inclineMatrix, accelValues, compassValues);
if(cek){
SensorManager.getOrientation(inR, prefValues);
mInclination = SensorManager.getInclination(inclineMatrix);
//display every 30th values
if(counter++ % 30 == 0){
//do your code, what you want to do to the result
counter = 1;
}
}
and everything work well

Make sure that you have registered your listeners to listen to the accelerometer, magmetic field and gyro (optional). You do this in the onResume method. If you forget to do this you will get "false" return value when calling getRotationMatrix.
I hope this helps!
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
// do more staff here..
}
protected void onResume() {
super.onResume();
mSensorManager.registerListener(
this,
mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),
SensorManager.SENSOR_DELAY_NORMAL );
mSensorManager.registerListener(
this,
mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD),
SensorManager.SENSOR_DELAY_NORMAL );
mSensorManager.registerListener(
this,
mSensorManager.getDefaultSensor(Sensor.TYPE_GYROSCOPE),
SensorManager.SENSOR_DELAY_NORMAL );
}
protected void onPause() {
super.onPause();
mSensorManager.unregisterListener(this);
}

The problem is with this part of code:
if(event.accuracy == SensorManager.SENSOR_STATUS_UNRELIABLE)
return;
For accelerometer event.accuracy return SensorManager.SENSOR_STATUS_UNRELIABLE that is why gravity is always null.

how to run onLongClick Event continously?

Is it possible to implement a fast forward button using the onLongClick button event?
EDIT
i used runnable inside the onlongclicklistner and adding the code for reference who needs :)
Button.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
final Runnable r = new Runnable()
{
public void run()
{//do the forwarding logic here
if(Button.isPressed()){
Button.postDelayed(this, 1000); //delayed for 1 sec
}else{
Button.postInvalidate();
Button.invalidate();
}
}
};
Button.post(r);
return true;
}
});

In your onLongClick event, set a member variable (example: mShouldFastForward) to true.
In the rest of your code (perhaps each frame played?) check if mShouldFastForward == true; if so, perform a fast-forward on that frame.
Use an onTouch event to capture the MotionEvent.ACTION_UP to set mShouldFastForward to false.

I have done it in this project (the project is not finished (ie polished) but fast forward works):
https://bitbucket.org/owentech/epileptic-gibbon-android
Take a look at playerfragment.java :
I handle this by using Threads to fast forward the mediaplayer.
Example code from project:
/*******************************/
/* Fast-Forward button actions */
/*******************************/
ffbutton.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View arg0, MotionEvent event) {
switch (event.getAction() ) {
case MotionEvent.ACTION_DOWN:
arrays.fastforwardpressed = true;
FastForwardThread newFFThread = new FastForwardThread();
arrays.fastforwardfrom = mp.getCurrentPosition();
arrays.fastforwardto = arrays.fastforwardfrom;
newFFThread.start();
break;
case MotionEvent.ACTION_UP:
arrays.fastforwardpressed = false;
mp.seekTo(arrays.fastforwardto);
break;
}
return true;
}
});
public class FastForwardThread extends Thread
{
public FastForwardThread()
{
super("FastForwardThread");
}
public void run()
{
while (arrays.fastforwardpressed == true)
{
arrays.fastforwardto = arrays.fastforwardto + 10000;
int fastforwardseconds = arrays.fastforwardto / 1000;
int hours = fastforwardseconds / 3600, remainder = fastforwardseconds % 3600, minutes = remainder / 60, seconds = remainder % 60;
String Hours = Integer.toString(hours);
String Minutes = Integer.toString(minutes);
String Seconds = Integer.toString(seconds);
if (Hours.length() == 1)
{
Hours = "0" + Hours;
}
if (Minutes.length() == 1)
{
Minutes = "0" + Minutes;
}
if (Seconds.length() == 1)
{
Seconds = "0" + Seconds;
}
arrays.formattedfftime = Hours + ":" + Minutes + ":" + Seconds;
fastforwardHandler.sendEmptyMessage(0);
try
{
sleep(100);
} catch (InterruptedException e)
{
e.printStackTrace();
}
}
}
}

Android App only working One time, then crashes

Okay so I am having a problem getting my app to work. Basically I have an game that needs to get a few pictures and Strings from the user. I have an opening screen (OpeningScreen) that acts as a splash screen that opens up the menu (MenuScreen). From there the user can pick to go to the game or go to the activity that shows the current pictures (PickScreen). The user can go to that activity and from there open up another activity that gives a larger version of the picture they currently have picked or a default picture (PicOne). Here the user has the option to take a new picture and change the current Strings. For the most part all of it works great. My problem occurs when:
After the user picks a picture and backs out of the app. The next time they open it, it will force close either when I go back to PickScreen or after I press done after taking a new picture and sometimes when I go to PicOne activity. It does not do the same thing everytime, it just crashes at one of those points.
The other issue happens when I change the 3 String names. After pressing save and going back to PickScreen, the app crashes when going back to PicOne or if I back out of the app crashes when going from MenuScreen to PickScreen.
I know this is a lot of code to look at, but I have spent a lot of time looking around and getting code from different places for this app and I am at a point that I cannot figure out. I figure there are many people with more knowledge than me out there, so I am asking for your help. I know that you cannot just ask a question without showing you have been doing any work, so here it is.
Why does may app work perfectly once and then crash in various spots the second time in? By the way it does work fine after the force close, again only once. And why does it force close when I change the Strings?
Thanks everyone!!

Logcat will give you a stack trace, and then use debug to pinpoint the place where it's crashing. Debugging a modern application by reading through code, especially OOP code, is nearly impossible.

This was probably caused by the fact the AOS does not closes apps really but you might think is does. So on the next start AOS doesn't start your app "from the scratch" but it raises your undead cached app. And since your logic wasn't expected that your app crashes. I'm pretty sure it starts OK once again right after the crash but the next start once again crashes -> the loop. So to avoid that use System.exit(0) (most advanced devs gonna say its a bad practice) to ensure your app wont became a zombie OR change the logic of your app so it wont crash on the next start cuz the main activity is still there.
