I am trying to make speech recognition in a surface view work. I am getting one small error.
Error:
It's not drawing the text but its drawing the background.
This line(#64):
c.drawARGB(255, 0, 0, 255); //works
p.setTextSize(50);
p.setColor(Color.WHITE);
c.drawText("mText: "+mText, 500, 500, p); //does not work

I thought my class was a context? What am I doing wrong.
If you are passing the Context to your constructor you should use: sr = SpeechRecognizer.createSpeechRecognizer(context);

Been through hell coding my first android app.
E/Camera: Error 2 in Logcat whenever camera is used (the error code is for multiple camera uses)
I have attached the entire project if you want to and can run it. Kindly help.

Here are updated files. It seems removing statements which release camera seems to remove errors of using camera after releasing. Unlocking the camera in onPause() removed-> E/Camera: Error 2

So I have an application which has to monitor and range after beacons and than calculates the position of the user. After calculating this , the value is passed to the Wayfindigoverlayactivity.class where the value should be putt on the map with the blue dot.
I don know how to assign the value to the blue dot but before that my application is working on an endless loop and is opening the activity on ranging about 100x .

The second class is not fully posted , only where I make changes.
The intent in the second class is in the OnCreate part
The location is calculated in the logcat , the only problem is that the application is working in a loop
Please help me , I am stuck. Thanks
I guess, you only need to open RangingActivity from onCreate() of WayFindingOverlayActivity if center is null. This means, we need to open RangingActivity to get the value for center. Doing null check for the center will also ensure that the application doesn't go in loop and proceed when we have the value for center. The code in the onCreate() of WayFindingOverlayActivity may look like this :
// edited here
Bundle extras = getIntent().getExtras();
if(extras == null){
Intent myIntent = new Intent(this, RangingActivity.class);
this.startActivity(myIntent);
} else{
LatLng center = extras.getParcelable("b");
Log.d("Location!!", center);
// call showLocationCircle() to show the blue dot
showLocationCircle(center, yourAccuracyRadius);
}
I am trying to play some rtsp video on custom textureview.Video is playing for the first time but when I go to second activity where the same video is played (not reinstantiated,same session but with different textureview) there it is playing and coming back to first activity where I am setting the sureface again in onResume textureview is still showing the content where it was left for the first time.Interesting fact is like video is still playing, just it is not visible in the textureview and if I go to second screen like before it is showing.I tried both releasing the surfacetexture and not releasing, tried also releasing the surface which I am holding a reference in the first activity for future use, not any of those seems to work.What can be the possible reason?
in onResume I am checking if app is coming back from app drawer or full screen activity.Where making the app go to background by clicking home button and coming back to app from app drawer video is playing.Only when coming back from full screen it's not working.

I'd like to check GPS both when the app is started and when the refresh button is hit, and use those data points, in the form of mLatitude and mLongitude to call the weather api. Eventually I'm going to geocode the city but right now for debugging purposes I'm outputting the GPS coordinates to the locationLabel textview.

Here are two things you can try:
1. Please ensure you have included the ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION permissions in your manifest. If your app targets Android API 23 and above, you will need to include runtime permission handling.
2. Instead of having a LocationListener object as a class member, you should have your Service implement it as an interface and implement its onLocationChanged() method.
Apart from this, you really should consider using the location APIs' in Google Play Services, rather than those in AOSP (i.e. android.location).
See Making Your App Location-Aware
I am working on an android app and am trying to figure out how to get a popup confirmation window to display with confirm and cancel buttons when a button is pressed.
Here is the creation of the alert.
final AlertDialog.Builder alertBuilder = new AlertDialog.Builder(activity);
alertBuilder.setTitle("Your Title");
alertBuilder.setMessage("Your Messages");
alertBuilder.setPositiveButton("Confirm", new OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Do something with value!
}
});
alertBuilder.setNegativeButton("Cancel", new OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
Here is the call to show.
Sprite p2 = new Sprite(goldMult, 25, 450, WIDTH, HEIGHT,
resourceManager.spriteRegion, vbom) {
/**
* #see org.andengine.entity.shape.Shape#onAreaTouched(org.andengine.input.touch.TouchEvent, float, float)
*/
#Override
public boolean onAreaTouched(final TouchEvent sceneTouchEvent, final float touchAreaLocalX,
final float touchAreaLocalY) {
AlertDialog alert = alertBuilder.create();
alert.show();
I am getting this exception:
java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
I saw a post with a similar issue here
However I am confused on how to implement this with my onAreaClicked event.
Thanks for any help in advanced
andengine uses opengl so you might want to create a handler to execute your dialog on the opengl thread
public Handler handler;
then
handler = new Handler() {
#Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 0:
AlertDialog alert = alertBuilder.create();
alert.show();
break;
}
}};
then to use it
handler.sendMessage(Message.obtain(handler, 0));
something along those lines
EDIT: class using handler for looper prepare opengl

I figured out the answer by wrapping the Alert in a new thread
activity.runOnUiThread(new Runnable() {
#Override
public void run() {
AlertDialog.Builder alert = new AlertDialog.Builder(activity);
alert.setTitle("");
alert.setMessage("");
alert.setPositiveButton("Buy", new OnClickListener() {
#Override
public void onClick(DialogInterface arg0, int arg1) {
}
});
alert.setNegativeButton("Cancel", new OnClickListener() {
#Override
public void onClick(DialogInterface arg0, int arg1) {
}
});
alert.show();
}
});
