问题背景：
今天做Intent ACTION_PICK 相册读取, 已经在AndroidManifest中添加了权限，
然后选取后，图片无法显示。
原因是：android6.0之后不仅需要在Mainfest里面添加权限，还需要添加运行时权限private static final int WRITE_PERMISSION = 0x01;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
requestWritePermission();
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
if(requestCode == WRITE_PERMISSION){
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.d(LOG_TAG, "Write Permission Failed");
Toast.makeText(this, "You must allow permission write external storage to your mobile device.", Toast.LENGTH_SHORT).show();
finish();
}
}
}
private void requestWritePermission(){
if(checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)!=PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},WRITE_PERMISSION);
}
}
