getting a permission error even after permission read_contacts is declared

So I initially only wanted to access contact names, and I only declared my permission in the manifest. My code was working fine then. But now I'm trying out accessing the contact number too, and that's giving me the following in logcat:

This is the relevant code within getContactName()

And the relevant code within getContactNumber()

Problem saving data and transfering to another activity (using FireBase)

I'm having problems while attempting to save data input (from the user) via two EditText and transferring it to another activity where it should be displayed as a ViewText.
Code from activity/data input
public class DatosBasicos extends AppCompatActivity {
EditText presion;
EditText ritmo;
Button atriaje;
String valorritmo;
String valorpresion;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_datos_basicos);
atriaje = (Button) findViewById(R.id.triaj);
presion = (EditText) findViewById(R.id.presion);
ritmo = (EditText) findViewById(R.id.ritmo);
atriaje.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
valorritmo = ritmo.getText().toString();
valorpresion = presion.getText().toString();
Intent i = new Intent(DatosBasicos.this, Triaje.class);
i.putExtra("PRESION",valorpresion);
i.putExtra("RITMO",valorritmo);
startActivity(i);
finish();
}
});
}
}
Code from activity/data output
public class Triaje extends AppCompatActivity {
TextView rit, pres;
String ritS, presS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_triaje);
rit = (TextView) findViewById(R.id.ritmoval);
pres = (TextView) findViewById(R.id.presionval);
ritS = getIntent().getExtras().getString("PRESION");
presS = getIntent().getExtras().getString("RITMO");
rit.setText(ritS);
pres.setText(presS);
}
}

WHAT SHOULD THE APP DO
I expect to get my data input into my Triaje activity and displayed in the two corresponding ViewText.
I get the following error: "App keeps stopping"

Is it possible to debug the system ? Then you clearly understand exactly where the it gives you error! Then tell exactly in which line it gives error!

Playing audio WITHOUT raw folder in Android (JAVA)

Trying to add a song to the MediaPlayer without R.raw.audiofilename. Making a music player and I obviously don't have the audio file being packaged with the app.
More detail: I am creating buttons to add to a scroll view, and on click, play the song.
The on click method seems to be where the error happening.
private void addSongs() {
Toast.makeText(this, "Searching", Toast.LENGTH_SHORT).show();
ContentResolver cr = this.getContentResolver();
Cursor cursor = cr.query(BASE_URI, BASE_PROJECTION, BASE_SELECTION, null, BASE_SORTORDER);
int count;
if (cursor != null) {
count = cursor.getCount();
if (count > 0) while (cursor.moveToNext()) createButton(cursor);
}
}
private void createButton(final Cursor cursor) {
final String TITLE = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
final String PATH = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
Button button = new Button(this);
button.setText(TITLE);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
MediaPlayer mediaPlayer = MediaPlayer.create(
MainActivity.this, Uri.parse(Environment.getExternalStorageDirectory().getPath()
+ "Music/" + TITLE + ".m4a")
);
mediaPlayer.start();
}
});
songList.addView(button);
}
This is pretty much all the code so far in the program, I am worried that my logic is the error here.

I'd guess my issue is in one of two places, either getContentResolver().query needs to use some newer method. OR the getColumnIndex(MediaStore.Images.ImageColumns.DATA) MediaStore is the incorrect way to deal with the newer cloud based photo apps.

A URI does not mean there is a file. An app is able to provide the contents through any mechanism it wants (a local file, a local file in a private directory you can't read, streamed over the internet, built dynamically on the fly).
Instead, you should use ContentResolver.openInputStream(contentUri) to get the contents from a URI. You can then transform that into a Bitmap via BitmapFactory.decodeStream()
