android 6.0 内部SD卡權限管理的方法

android 6.0以後，權限的管理方法就不僅局限于androidManifest.xml了，APK 如果需要權限，必須要在代碼裡實作權限的申請。

下面是實時檢視權限的許可情況和實時撤銷權限許可的指令（不用每次都去: 設定->應用->xxx應用->應用資訊->權限->權限清單，修改權限的許可）的方法

• Use the adb tool to manage permissions from the command line:
  • List permissions and status by group: 這個隻是列出裝置的所有的危險權限，并沒有指令來顯示某個應用的權限的許可情況（這點不好）

    $ adb shell pm list permissions -d -g      

  • Grant or revoke one or more permissions:

    $ adb shell pm [grant|revoke] <permission-name> ...      

• Analyze your app for services that use permissions.

檢視内部SD權限的讀取權限

group:android.permission-group.STORAGE

  permission:android.permission.READ_EXTERNAL_STORAGE

  permission:android.permission.WRITE_EXTERNAL_STORAGE

權限的申請判斷代碼如下：

/***
     group:android.permission-group.STORAGE
     permission:android.permission.READ_EXTERNAL_STORAGE
     permission:android.permission.WRITE_EXTERNAL_STORAGE
     ***/
    private static final int REQUEST_EXTERNAL_STORAGE = 1;
    private static String[] PERMISSIONS_STORAGE = {
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE };
    private boolean verifyStoragePermissions(Activity activity) {

        if(Util.SDK_INT < 23) /*******below android 6.0*******/
        {
            return true;
        }

        // Check if we have write permission
        int permission = ActivityCompat.checkSelfPermission(activity,
                Manifest.permission.READ_EXTERNAL_STORAGE);
        if (permission != PackageManager.PERMISSION_GRANTED) {
            // We don't have permission so prompt the user
            ActivityCompat.requestPermissions(activity,PERMISSIONS_STORAGE,
                    REQUEST_EXTERNAL_STORAGE);
            return false;
        }
        else
        {
          return true;
        }
    }
           

如果verifyStoragePermissions 傳回時false，那麼需要實作權限的申請處理，實作onRequestPermissionResult

@Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case REQUEST_EXTERNAL_STORAGE: {
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    /×××do request function(into apk)×××××/
                } else {

             Toast.makeText(getApplicationContext(),
             "storage permission denied,it will exit apk",
             Toast.LENGTH_LONG).show();
                    
                     /×××do request function(exitapk)×××××/
                      finish(); 
                      } 
                    }
           break; 
           default: 
           super.onRequestPermissionsResult(requestCode, permissions, grantResults);
           break; 
        }
       }
      }
           

如果verifyStoragePermissions傳回true則直接進入APK或Activity.
