记又一次被 Android 动态权限请求坑的经历

被动态权限获取安排的明明白白。

谁知道那家伙用的是 5.0 的系统 。。。所以说如果用了 ContextCompat 和 ActivityCompat 就不需要自己再去判断一次版本号了…

- if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
-     if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
-         ActivityCompat.requestPermissions(this,
-                 new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
-                 READ_REQUEST_CODE);
-     } else {
-         dosth();
-     }

+ if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
+     ActivityCompat.requestPermissions(this,
+             new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
+             READ_REQUEST_CODE);
+ } else {
+     dosth();
+ }
