棉花糖运行时权限onRequestPermissionsResult在运行playstore Build Apk时也未调用，但可以正常调试Apk正常工作。任何人都可以帮助我..谢谢。
这是我的代码
private void EnablePermissions()
{
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(this,android.Manifest.permission.RECORD_AUDIO)) {
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(this, new String[] { android.Manifest.permission.RECORD_AUDIO },
MY_PERMISSIONS_REQUEST_RECORD);
Toast.makeText(MainActivity.this, "Permission Request", Toast.LENGTH_SHORT).show();
// result of the request.
}
// Add a marker in Sydney, Australia, and move the camera.
if (ContextCompat.checkSelfPermission(MainActivity.this,
android.Manifest.permission.RECORD_AUDIO) != PackageManager.PERMISSION_GRANTED) {
Toast.makeText(MainActivity.this, "checkSelfPermission ", Toast.LENGTH_SHORT).show();
return;
} else {
Log.d("Permission Denied", "Permission Failed to enable");
Toast.makeText(MainActivity.this, "Permission Failed to enable", Toast.LENGTH_SHORT).show();
}
}
OnRequestPermissionResult方法
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
try {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_RECORD: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// contacts-related task you need to do.
ChatActivity();
} else {
Toast.makeText(MainActivity.this, "Permission denied Chat ", Toast.LENGTH_SHORT).show();
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
return;
}
// other 'case' lines to check for other
// permissions this app might request
}
} catch (Exception e) {
Log.e(Constants.LOG, e.getMessage());
}
}
最佳答案
这是正确的方法https://stackoverflow.com/a/35495372/4493133。我在下面做基本上相同的事情。
这是一个有关如何使其适用于我的代码的示例
private void requestStoragePermission() {
/*
We don't have permission so prompt the user
If permission is not granted control goes to onRequestPermissionResult
*/
ActivityCompat.requestPermissions(
this,
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE
);
}
onRequestPermissionsResult方法：
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode) {
case REQUEST_EXTERNAL_STORAGE:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.d("PERMISSION", "Storage permission granted");
} else {
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
showMessageOkCancel("You need to allow access to Storage to use the offline timetables",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case DialogInterface.BUTTON_POSITIVE:
requestStoragePermission();
break;
case DialogInterface.BUTTON_NEGATIVE:
Toast.makeText(MainActivity.this, "Storage permission required to continue", Toast.LENGTH_LONG)
.show();
finishAffinity();
break;
}
}
});
} else {
Toast.makeText(this, "Go to settings and enable storage permissions", Toast.LENGTH_LONG)
.show();
finishAffinity();
}
}
}
}
showMessageOkCancel方法：
private void showMessageOkCancel(String message, DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(this)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", okListener)
.create()
.show();
}
说明：
在您的主代码中，您仅需要StorageStoragePermission（）。
无论是否授予权限，onRequestPermissionsResult都将运行。
如果授予了权限，那就好了。
如果未授予许可，则如果是第一次请求许可，则shouldShowRequestPermissionRationale（）将返回true。然后，我提示另一个带有一些说明的对话框，以给用户另一个启用权限的机会。
但是，如果选中了“不再询问”，则shouldShowRequestPermissionRationale将返回false。 requestPermissions对话框将不再弹出。用户必须去手动启用权限。
注意，您不必完成finishAffinity（）。您可以只禁用需要该权限的代码部分。
