私はAndroidで新しく、実行時のアクセス権に問題があります。 私のアプリは電話のすべての連絡先を読んでリストを抽出します。問題は私の電話の連絡先を読む許可です。私が初めてアプリを開くと、アプリがクラッシュしてから連絡先を読む許可を求めます。 もう一度開くと、2回目にアプリに問題があります。 だから、問題がクラッシュする前に許可を求めることです... 私MainActivityは次のとおりです。もちろんAndroid Nougat実行時アクセス許可
public class MainActivity extends AppCompatActivity {
public static final int REQUEST_CODE_ASK_PERMISSIONS = 123;
ReadContacts values = new ReadContacts();
@Override
protected void onCreate(Bundle savedInstanceState) {
// Readcontacts val = new Readcontacts();
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Get ListView object from xml
/*
int hasWriteContactsPermission = checkSelfPermission(Manifest.permission.READ_CONTACTS);
if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS},
REQUEST_CODE_ASK_PERMISSIONS); }*/
final ListView listView = (ListView) findViewById(R.id.list);
final int frth = listView.getHeight();
ToggleButton toggle = (ToggleButton) findViewById(R.id.toggleButton9);
toggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
for (int i = 0; i < listView.getChildCount(); i++) {
double max = 2 * 90;
Resources r = getResources();
float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 72, r.getDisplayMetrics());
listView.getChildAt(i).setMinimumHeight((int) px);
}
// The toggle is enabled
} else {
// The toggle is disabled
for (int i = 0; i < listView.getChildCount(); i++) {
listView.getChildAt(i).setMinimumHeight(frth);
}
}
}
});
String[] values = new String[1000000];
int temp =0 ;

私はすでに追加
<uses-permission android:name="android.permission.READ_CONTACTS" />
任意のアイデアと私のマニフェストを変更？

エラーは、Android 6.0（APIレベル23）で始まり
