I'm kind of new to android, actually this is my first app. The app is not completed through, i wanted to test the UI, it works fine on AVD, but when I copy the .apk file from bin folder to my phone, it installs fine, but wont work ends up with force close error. I have no idea what's the problem, I saw on other post about parsing the content in edittext, i took out the layout and ran it again still not working. again, I am new to this, please help me.

Read the logcat: noSuchMethodError on line 223. Double click that line in the logcat and you will end up on line 223 of your MainActivity. Tell us the code.
CscCountry is not German?
Or you are running on a device that does not know getActionBar().

I am trying to auth google user in WebView, I found a good solution for these days, it works fine for google login, but I cannot disable dialog in other urls like (, sms: , smsto:)
Example Situation: User click on telephone number in my app, it will open the phone dial, but when he returns back.. there is a empty dialog window with close button, i use it for google login with JS.
How can i close this dialog message inside the shouldOverrideUrlLoading()? Or is there any better solution to not open other links in the dialog? How can i improve my code to solve my problem? Thank you guys!

Background:
* Full Stack developer training (recently finished studies).
* Am not very (putting it mildly) Java savvy.
for the past couple of days I've been trying to make the tapping on a OneSignal notification open the app according to the URL stored in the notification payload.
What did work was:
* If the app is showing on the screen and you press the notification it works fine and opens it accordingly.
It does ALMOST work in the way that if the app is in the background and you press the notification it either:
1. Launches the app but on the main page
OR
2. Doesn't launch the app but when you actively go back to the app it shows the correct content (according to the URL of the notification)
Following is the code:
Thank you!

I'm trying to run a code in my android studio emulator but after I run it, the emulator keeps showing "(App name) has stopped. Open app again".
This is an app to get accelerometer and gyro sensor data from Android wear.
I've checked the logcat and found this error in the process.

Can someone help me out? I got this code from some source and I don't know how to fix it since the logcat is showing a long fatal exception script highlighted in red. Thank you, I'll really appreciate it if someone can help.
From the error message in LogCat you can read that mSensor is null when you try to execute
mTextTitle.setText(mSensor.getStringType());
This means that the your sensor manager is unable to find a default sensor that matches the requested type
mSensor = mSensorManager.getDefaultSensor(mSensorType);
as stated in the documentation.

You are starting Thread at onCreate()
this.Thread1 = new Thread(new Thread1());
this.Thread1.start();
Then again starting the same thread at onClick()
Your problem is on this line:
Thread Thread1 = null;
You are setting the thread to a null value and that's where it says the error is coming from. Try assigning it a different value and see if that changes anything.
I am using Android Studio 2.0(preview).
In order to display some info about certain movies , I downloaded Themoviedb.com API Wrapper by holgerbrandl
, added a dependency but just after I add two lines of the wrapper-related code I get a lot of errors I'm not familiar how to deal with.
TmdbMovies movies = new TmdbApi("myAPIkey_here").getMovies();
MovieDb movie = movies.getMovie(5353, "en");
I'm a very inexperienced newbie - thus the need of your help :)
If any details needed, please remind me to add them.

I'm actually learning TheMovieDB API for a school project right now.
Apparently, whenever you want to use the network on android and connect to something, you need to put the statement inside an async task; something to do with network connections not working on the main thread.
To do this you can create a custom AsyncTask in your activity like so:
protected class MovieTask extends AsyncTask<Void, Void, MovieDB> {
protected MovieDB doInBackground(Void... v) {
TmdbMovies movies = new TmdbApi("myAPIkey_here").getMovies();
MovieDb movie = movies.getMovie(5353, "en");
return movie;
}
protected void onPostExecute(MovieDB movie) {
// Do something with movie
}
}
And your MainActivity onCreate would look like
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
MainText = (TextView) findViewById(R.id.main_text);
MovieTask mt = new MovieTask();
mt.execute();
}
