Question

android 获取相册图片，使用Intent.ACTION_GET_CONTENT时，提示java.lang.SecurityException，怎么弄？

java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaDocumentsProvider uri content://com.android.providers.media.documents/document/image/87 from pid=6995, uid=10091 requires android.permission.MANAGE_DOCUMENTS, or grantUriPermission()

Answer 1

if (Build.VERSION.SDK_INT >= 23) {
int checkCallPhonePermission = ContextCompat.checkSelfPermission(context, android.Manifest.permission.READ_EXTERNAL_STORAGE);
if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions((Activity)context,new String[]{android.Manifest.permission.READ_EXTERNAL_STORAGE},223);
return;
}else{

openPhotos();//调用具体方法
}
} else {

openPhotos();//调用具体方法
}

public void openPhotos(){
Intent intent2 = new Intent(Intent.ACTION_GET_CONTENT);
//Intent intent2 = new Intent(Intent.ACTION_PICK);
intent2.setType("image*//*");
((Activity)context).startActivityForResult(intent2, TACKPHOTOFLAG_PHOTO);
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
//就像onActivityResult一样这个地方就是判断你是从哪来的。

case 223:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission Granted
openPhotos();
} else {
// Permission Denied
Toast.makeText(YhUploadActivity.this, "很遗憾你把相册权限禁用了。请务必开启相册权限享受我们提供的服务吧。", Toast.LENGTH_SHORT)
.show();
}
break;
default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}

Answer 2

 <uses-permission android:name="android.permission.CAMERA" />
 <uses-feature android:name="android.hardware.camera" />
 <uses-feature android:name="android.hardware.camera.autofocus" />
确保你有加这些在mainfest

Answer 3

应该是没有配置权限吧

追问

写了权限，可以确定
