(轉)安卓6.0系統權限申請android.permission.WRITE_SETTINGS （亮度調節）

原地址：http://blog.csdn.net/hnkwei1213/article/details/54947339

 

 

app用到了調整系統亮度的功能，在清單文件中添加了android.permission.WRITE_SETTINGS權限，但運行在6.0系統一直報錯：java.lang.SecurityException: so.wih.android.jjewatch was not granted this permission: android.permission.WRITE_SETTINGS.

解決方法以下：

1.  
   //設置系統亮度
2.  
   if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
3.  
   if (!Settings.System.canWrite(context)) {
4.  
   Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS);
5.  
   intent.setData(Uri.parse("package:" + context.getPackageName()));
6.  
   intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
7.  
   context.startActivity(intent);
8.  
   } else {
9.  
   //有了權限，具體的動做
10.  
    Settings.System.putInt(getContentResolver(),
11.  
    Settings.System.SCREEN_BRIGHTNESS, progress);
12.  
    data2 = intToString(progress, 255);
13.  
    tvSunlightValue.setText(data2 + "%");
14.  
    }
15.  
    }
