private void callPhone() {
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:456"));
startActivity(intent);
}
Mas deu o erro:
Caused by: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.CALL dat=tel:xxx cmp=com.android.server.telecom/.components.UserCallActivity } from ProcessRecord{3e464e1 3861:br.com.localhost8080.myapp/u0a62} (pid=3861, uid=10062) requires android.permission.CALL_PHONE
Então fui no AndroidManifest.xml e coloquei a permission:
<uses-permission android:name="android.permission.CALL_PHONE"/>
Mas aí aconteceu o erro:
Caused by: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.CALL dat=tel:xxx cmp=com.android.server.telecom/.components.UserCallActivity } from ProcessRecord{ea870e6 4476:br.com.localhost8080.myapp/u0a62} (pid=4476, uid=10062) with revoked permission android.permission.CALL_PHONE
Para resolver usei o código abaixo pois a permission CALL_PHONE é level dangerous e você precisa solicitar permissao para o usuário:
private static final int MY_PERMISSIONS_REQUEST_CALL_PHONE = 1;
public void onClick(View view) {
int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE);
if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, MY_PERMISSIONS_REQUEST_CALL_PHONE);
} else {
callPhone();
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_CALL_PHONE: {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
callPhone();
}
}
}
}
private void callPhone() {
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:456"));
startActivity(intent);
}
