我想获取手机的 simcard 当前号码并将其显示在 toast 消息中

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);       
  //  startActivity(browserIntent);y

    TelephonyManager phoneManager = (TelephonyManager) 
            getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE);
        String phoneNumber = phoneManager.getLine1Number();
        Context context = getApplicationContext();
        CharSequence text = phoneNumber;
        int duration = Toast.LENGTH_SHORT;

        Toast toast = Toast.makeText(context, text, duration);
        toast.show();


//   setContentView(R.layout.activity_main);       
}

但是android一直强迫它关闭。

错误日志：

您可以在 androidManifest 文件中设置 READ_PHONE_STATE 权限

 <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
