How to fix StrictMode policy violation in android while fetching all mobile number?
11,373
You should not perform the work on the UI thread, but instead create a worker thread and do most of the work there. The simplest solution is to use an AsyncTask:
public class StrictModeActivity extends AppCompatActivity {
private static final String TAG = StrictModeActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectNetwork()
.penaltyLog()
.penaltyDeath()
.build());
new QueryForPhoneNumberTask().execute("your contact display name");
}
private class QueryForPhoneNumberTask extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... strings) {
String mFmFmUserMobile = null;
String contactId = strings[0];
final String[] projection = new String[]{
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.TYPE,
};
final Cursor phone = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection,
ContactsContract.Data.DISPLAY_NAME + "=?",
new String[]{contactId},
null);
if (phone.moveToFirst()) {
final int contactNumberColumnIndex = phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
//final int contactTypeColumnIndex = phone.getColumnIndex(Phone.TYPE);
while (!phone.isAfterLast()) {
mFmFmUserMobile = phone.getString(contactNumberColumnIndex);
//final int type = phone.getInt(contactTypeColumnIndex);
phone.moveToNext();
}
}
phone.close();
if (mFmFmUserMobile != null && mFmFmUserMobile.contains(" ")) {
mFmFmUserMobile.replace(" ", "");
}
//mFmFmUserMobile.substring(mFmFmUserMobile.length()-10,mFmFmUserMobile.length()
return mFmFmUserMobile;
}
@Override
protected void onPostExecute(String result) {
Log.d(TAG, result);
}
}
}

I am fetching all mobile numbers using cursor query. I have enabled strict mode getting this exception.
Here is my code for fetching mobile number :
public String queryForPhoneNumber(String contactId) { final String[] projection = new String[] { Phone.NUMBER, Phone.TYPE, }; final Cursor phone = getActivity().getContentResolver().query( Phone.CONTENT_URI, projection, Data.DISPLAY_NAME + "=?", new String[]{contactId}, null); if(phone.moveToFirst()) { final int contactNumberColumnIndex = phone.getColumnIndex(Phone.NUMBER); //final int contactTypeColumnIndex = phone.getColumnIndex(Phone.TYPE); while(!phone.isAfterLast()) { mFmFmUserMobile = phone.getString(contactNumberColumnIndex); //final int type = phone.getInt(contactTypeColumnIndex); phone.moveToNext(); } } phone.close(); if(mFmFmUserMobile.contains(" ")){ mFmFmUserMobile.replace(" ", ""); } //mFmFmUserMobile.substring(mFmFmUserMobile.length()-10,mFmFmUserMobile.length() return mFmFmUserMobile; }Exception :
