我是android studio的新手,在我的第一个应用程序中我想构建一个sos应用程序,我的sos应用程序专门通过短信发送一条消息与当前位置。当我第一次构建它时,它只适用于android 5.0及以下版本,它不能在6.0及以上版本中工作,现在我已经尝试查看logcat,而logcat说它需要获得发送短信的权限所以我给了它是使用本段下面的代码的权限,现在它在Android 6.0中运行,但它没有发送消息... {if(checkselfpermission(Manifest.permission.SEND_SMS)==PackageManager.PERMISSION GRANTED);}
你能帮助我吗?这是我的文件

我希望你能帮助我。
答案 0 :(得分:0)
你可以试试这个: -
在Manifest
-
<uses-permission android:name="android.permission.SEND_SMS" />
在您的活动中使用此运行时权限
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.SEND_SMS},1);
