Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/i
最近在做调用系统相册，选择多照片问题，遇到了一个错，发现用原有的设置权限方式是不行的，总结一下解决办法，报错如下：
- ComponentInfo{com.example.chenkui.testpic/com.example.chenkui.testpic.TestPicActivity}:

AndroidManifest.xml
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE" />在onCreate()里面添加：
private static final int REQUEST_PERMISSION = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image_bucket);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
int hasWritePermission = checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);
int hasReadPermission = checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE);
List permissions = new ArrayList();
if (hasWritePermission != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
} else {
// preferencesUtility.setString("storage", "true");
}
if (hasReadPermission != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.READ_EXTERNAL_STORAGE);
} else {
// preferencesUtility.setString("storage", "true");
}
if (!permissions.isEmpty()) {
// requestPermissions(permissions.toArray(new String[permissions.size()]), REQUEST_CODE_SOME_FEATURES_PERMISSIONS);
ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_PHONE_STATE},
REQUEST_PERMISSION);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case REQUEST_PERMISSION: {
for (int i = 0; i < permissions.length; i++) {
if (grantResults[i] == PackageManager.PERMISSION_GRANTED) {
System.out.println("Permissions --> " + "Permission Granted: " + permissions[i]);
} else if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
System.out.println("Permissions --> " + "Permission Denied: " + permissions[i]);
}
}
}
break;
default: {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
}
