Question

这是我们项目唯一尚未解决的问题。假设该应用已安装在某人的手机上。然后我们想通过向我/她发送一条与我们程序中的消息的body参数匹配的消息来启动应用程序。我遵循了一些代码，但似乎所有我尝试过的代码都没有用。请尊重。感谢那些慷慨帮助的人。

public class SmsReceiver extends BroadcastReceiver{

    public static String trigger = "";

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        SmsMessage[] msgs = null;
        String str="";
        String num="";
        Intent i = new Intent();
        i.setClassName("gavadev.com.autolaunch", "gavadev.com.autolaunch.NewAct");
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);



        if(bundle != null){
            Object[] pdus = (Object[]) bundle.get("pdus");
            msgs= new SmsMessage[pdus.length];


            for(int j =0 ;j<pdus.length; j++) {

                trigger = msgs[j].getMessageBody().toString();
                num = msgs[j].getOriginatingAddress();

                str += trigger;



            }
            Toast.makeText(context,"From: "+num+ " Message: " +trigger,Toast.LENGTH_LONG).show();
            if((trigger.equals("themessage"))&&(num.equals("thenumber"))){
                context.startActivity(i);

            }
        }
    }
}

这是我的Manifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="gavadev.com.autolaunch">

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <receiver android:name=".SmsReceiver">
            <intent-filter>
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

        <activity
            android:name=".NewAct"
            android:label="@string/title_activity_new"
            android:theme="@style/AppTheme.NoActionBar"></activity>
    </application>

</manifest>

*我在MainActivity.class上没有做任何事情
