Question

当我点击一个按钮时，我想将短信发送到固定号码（实际上在两个虚拟设备之间），但是当我按下它时会抛出此异常。

这里有一些简单的代码，我发现它应该适用于两台运行在vms中的手机，但这里并没有明显的原因

public class MainActivity extends AppCompatActivity{

 private Button button3;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button3= (Button) findViewById(R.id.SEND);
    }

 public void onClick(View view) {
        String number = "6942649512";
        String message= "Help";

        //Intent intent = new Intent(getApplicationContext(),MainActivity.class);
        // PendingIntent pi=PendingIntent.getActivity(getApplicationContext(),0,intent,0);

        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(number, null,message,null,null);


        Toast toast = Toast.makeText(getApplicationContext(), "Message sent!", Toast.LENGTH_SHORT);
        toast.show();

    }
}

我还在manifest.xml文件中添加了sms权限。

你的例外是：

Caused by: java.lang.SecurityException: Sending SMS message: uid 10079 does not have android.permission.SEND_SMS.

这意味着您无权发送短信。因此，请尝试将Android权限添加到Android Manifest中，如果您使用API 23＆gt; =，则需要请求用户权限。

ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.SEND_SMS},1);

AndroidManifest：

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

请详细了解runtime permissions。

尝试在Android中发送短信时抛出java.lang.IllegalStateException
