許可を扱うのは、処理する許可に変更するだけです
最初のチェック
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
} else {
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 666); // Comment 26
}
}
そしてエンドユーザーの入力を管理
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case 666: // User selected Allowed Permission Granted
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Snackbar s = Snackbar.make(findViewById(android.R.id.content), "Permission Granted", Snackbar.LENGTH_LONG);
View snackbarView = s.getView();
snackbarView.setBackgroundColor(Color.WHITE);
TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(Color.RED);
textView.setTextSize(18);
textView.setMaxLines(6);
s.show();
// do your work here
// User selected the Never Ask Again Option Change settings in app settings manually
} else if (Build.VERSION.SDK_INT >= 23 && !shouldShowRequestPermissionRationale(permissions[0])) {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);
alertDialogBuilder.setTitle("Change Permissions in Settings");
alertDialogBuilder
.setMessage("Click SETTINGS to Manually Set\n\n" + "Permissions to use Database Storage")
.setCancelable(false)
.setPositiveButton("SETTINGS", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", getPackageName(), null);
intent.setData(uri);
startActivityForResult(intent, 1000);
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
} else {
// User selected Deny Dialog to EXIT App ==> OR <== RETRY to have a second chance to Allow Permissions
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED) {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);
alertDialogBuilder.setTitle("Second Chance");
alertDialogBuilder
.setMessage("Click RETRY to Set Permissions to Allow\n\n" + "Click EXIT to the Close App")
.setCancelable(false)
.setPositiveButton("RETRY", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent i = new Intent(MainActivity.this, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
}
})
.setNegativeButton("EXIT", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
finish();
dialog.cancel();
}
});
