android6.0 之前，app許可權的申請都是在manifest中宣告即可。

android6.0開始增加許可權動態監測和申請。

尤其是使用androidstudio開發程式，如果在呼叫許可權介面之前，沒有申請許可權，就無法編譯

以gps 為例，許可權申請方式如下：

if (Build.VERSION.SDK_INT >= 23) {
    int checkPermission = ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.ACCESS_COARSE_LOCATION);
    if 
 
(checkPermission != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
Log.d("TTTT"
 
, "彈出提示");
}
}

location = lm.getLastKnownLocation(bestProvider);

申請許可權回撥

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
Log.e
 
(TAG,"onRequestPermissionsResult");
//requestpermisiion result , permission
}
