Android6.0_Permission permission control learning record

1. Request and check permissions, check which are dangerous permissions, and execute on the command line: adb shell pm list permissions -d -g to list dangerous permissions and permission groups

2. The following is the application for permission to make calls

 

public void onClick(View view) {
    switch(view.getId()){
        case R.id.callPhone:
            callPhone();
            break;
        case R.id.take_picture:
            takePicture();
            break;
        case R.id.downLoad_file:
            downloadFile();
            break;
    }

}

/**
 * 打电话
 */
private void callPhone() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) !=
            PackageManager.PERMISSION_GRANTED){
        //做权限申请处理
        //需要的参数，上下文，要请求的权限名称，和请求码
        ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CALL_PHONE},1);
    }else{
        doCallPhone();
    }
}

@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { switch(requestCode){ case 1: //打电话权限的回调处理  if (grantResults[0] == PackageManager.PERMISSION_GRANTED) { doCallPhone();  }else{ Toast.makeText(this,"您拒绝了这个权限，应用的部分功能将不能使用",Toast.LENGTH_LONG).show();  } break;  case 2: break;  case 3: break;  }

/**  * 执行打电话操作  */ private void doCallPhone() { Intent intent = new Intent(Intent.ACTION_CALL);  Uri data = Uri.parse("tel:"+"10086");  intent.setData(data);  this.startActivity(intent); }

 

 

其他的权限以此类推，但是这个有多个权限的话工作量就特别大，需要抽取出来，
