((Button) findViewById(R.id.dialbutton1)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent intent = new Intent(Intent.ACTION_DIAL); intent.setData(Uri.parse("tel: ")); startActivity(intent); } });

9. 2. How to make a phone call in Android. (Permission Required.)
((Button) findViewById(R.id.dialbutton1)).setOnClickListener(new View.OnClickListener() public void onClick(View view) { if(isPermissionGranted()){ call_action(); } } }); <uses-permission android:name="android.permission.CALL_PHONE"/>

10. 2. How to make a phone call in Android. (Permission Required.)
public void call_action(){ try { String phnum = "123456"; Intent callIntent = new Intent(Intent.ACTION_CALL); callIntent.setData(Uri.parse("tel:" + phnum)); startActivity(callIntent); } catch (SecurityException e) { Toast.makeText(this, "Permission Denied", Toast.LENGTH_SHORT).show(); } }

11. 2. How to make a phone call in Android. (Permission Required.)
public boolean isPermissionGranted() { if (Build.VERSION.SDK_INT >= 23) { if (checkSelfPermission(android.Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) { Log.v("TAG","Permission is granted"); return true; } else { Log.v("TAG","Permission is revoked"); ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, 1); return false; } } else { //permission is automatically granted on sdk<23 upon installation Log.v("TAG","Permission is granted"); return true; } }

12. 2. How to make a phone call in Android. (Permission Required.)
@Override public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case 1: { if (grantResults.length > && grantResults[0] == PackageManager.PERMISSION_GRANTED) { Toast.makeText(getApplicationContext(), "Permission granted", Toast.LENGTH_SHORT).show(); call_action(); } else { Toast.makeText(getApplicationContext(), "Permission denied", Toast.LENGTH_SHORT).show(); } return; } // other 'case' lines to check for other // permissions this app might request } }

13. 3. How can I open a URL in Android's web browser from my application?
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(" startActivity(browserIntent);

Implicit
Explicit

15. 4. Start an Activity with a parameter
Intent i = new Intent(this, TheNextActivity.class); i.putExtra(“parameter1", value1); startActivity(i); String value1 = extras.getStringExtra(“parameter1”);

16. 5. Start service in Android
startService(new Intent(this, UpdaterServiceManager.class));
Intent i = new Intent(this, Service1.class);
startService(i);

17. Logging Application Information
