Android - 尝试在不使用移动网络的情况下向自己发送假短信

Question

我正在尝试使用此应用向我的手机发送消息，但不使用网络，但我的代码不起作用。我遵循了一些教程，检查了 android dev 并没有找到任何东西（在我的 logcat 中我没有错误）。你能帮我找出我的问题吗？

我关于编译、编译器和电话的信息：

• Android Studio 1.0.1

• API 19 Android 4.4.4 (kitkat)

• 构建 19

• Android 手机版本 4.4.4

清单：

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

我的主要活动的功能：

Context context;
String sender;
String body;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //Get current context
    context = this;

    //App started
    Toast.makeText(context, "Started", Toast.LENGTH_LONG).show();

    CheckApp();
}

private void CheckApp() {

    sender = "1234";
    body = "Android sms body";

    //Get my package name
    final String myPackageName = getPackageName();

    //Check if my app is the default sms app
    if (!Telephony.Sms.getDefaultSmsPackage(this).equals(myPackageName)) {

        //Get default sms app
        String defaultSmsApp = Telephony.Sms.getDefaultSmsPackage(context);

        //Change the default sms app to my app
        Intent intent = new Intent( Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
        intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, context.getPackageName());
        startActivity(intent);

        //Write the sms
        WriteSms(body, sender);

        //Change my sms app to the last default sms app
        Intent intent2 = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
        intent2.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, defaultSmsApp);
        startActivity(intent2);
    }
    else{

        //Write the sms
        WriteSms(body, sender);
    }
}

//Write the sms
private void WriteSms(String message, String phoneNumber) {

    //Put content values
    ContentValues values = new ContentValues();
    values.put(Telephony.Sms.ADDRESS, phoneNumber);
    values.put(Telephony.Sms.DATE, System.currentTimeMillis());
    values.put(Telephony.Sms.BODY, message);

    //Insert the message
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        context.getContentResolver().insert(Telephony.Sms.Sent.CONTENT_URI, values);
    }
    else {
        context.getContentResolver().insert(Uri.parse("content://sms/sent"), values);
    }
}

嗯，这就是我想要做的，但使用的是我自己的应用程序，而不是下载到 Play 商店的应用程序 Fake Text Message。

制作假消息，我应该在我的默认短信应用上看到什么：

在 Mike M 的帮助下，我终于完成了我的程序。因此，这是您必须添加到应用程序中才能在不使用网络的情况下发送短信的代码：

清单：

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <!-- BroadcastReceiver that listens for incoming SMS messages -->
    <receiver android:name=".SmsReceiver"
        android:permission="android.permission.BROADCAST_SMS">
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_DELIVER" />
        </intent-filter>
    </receiver>

    <!-- BroadcastReceiver that listens for incoming MMS messages -->
    <receiver android:name=".MmsReceiver"
        android:permission="android.permission.BROADCAST_WAP_PUSH">
        <intent-filter>
            <action android:name="android.provider.Telephony.WAP_PUSH_DELIVER" />
            <data android:mimeType="application/vnd.wap.mms-message" />
        </intent-filter>
    </receiver>

    <!-- My activity -->
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <!-- Activity that allows the user to send new SMS/MMS messages -->
    <activity android:name=".ComposeSmsActivity" >
        <intent-filter>
            <action android:name="android.intent.action.SEND" />
            <action android:name="android.intent.action.SENDTO" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="sms" />
            <data android:scheme="smsto" />
            <data android:scheme="mms" />
            <data android:scheme="mmsto" />
        </intent-filter>
    </activity>

    <!-- Service that delivers messages from the phone "quick response" -->
    <service android:name=".HeadlessSmsSendService"
        android:permission="android.permission.SEND_RESPOND_VIA_MESSAGE"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.RESPOND_VIA_MESSAGE" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="sms" />
            <data android:scheme="smsto" />
            <data android:scheme="mms" />
            <data android:scheme="mmsto" />
        </intent-filter>
    </service>

</application>

主要活动：

Context context;
Button button;
String sender,body,defaultSmsApp;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //Get current context
    context = this;

    //Set composant
    button = (Button) findViewById(R.id.button);

    //Get default sms app
    defaultSmsApp = Telephony.Sms.getDefaultSmsPackage(context);

    //Set the number and the body for the sms
    sender = "0042";
    body = "Android fake message";

    //Button to write to the default sms app
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            //Get the package name and check if my app is not the default sms app
            final String myPackageName = getPackageName();
            if (!Telephony.Sms.getDefaultSmsPackage(context).equals(myPackageName)) {

                //Change the default sms app to my app
                Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
                intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, context.getPackageName());
                startActivityForResult(intent, 1);
            }
        }
    });
}

//Write to the default sms app
private void WriteSms(String message, String phoneNumber) {

    //Put content values
    ContentValues values = new ContentValues();
    values.put(Telephony.Sms.ADDRESS, phoneNumber);
    values.put(Telephony.Sms.DATE, System.currentTimeMillis());
    values.put(Telephony.Sms.BODY, message);

    //Insert the message
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        context.getContentResolver().insert(Telephony.Sms.Sent.CONTENT_URI, values);
    }
    else {
        context.getContentResolver().insert(Uri.parse("content://sms/sent"), values);
    }

    //Change my sms app to the last default sms
    Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
    intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, defaultSmsApp);
    context.startActivity(intent);
}

//Get result from default sms dialog pops up
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == 1) {
        // Make sure the request was successful
        if (resultCode == RESULT_OK) {

            final String myPackageName = getPackageName();
            if (Telephony.Sms.getDefaultSmsPackage(context).equals(myPackageName)) {

                //Write to the default sms app
                WriteSms(body, sender);
            }
        }
    }
}

在清单中添加内容后，您必须添加 4 个类：SmsReceiver、MmsReceiver、ComposeSmsActivity 和 HeadlessSmsSendService。您可以让它们为空，如下所示。

短信接收器：

public class SmsReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

    }
}

MmsReceiver：

public class MmsReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

    }
}

ComposeSmsActivity：

public class ComposeSmsActivity extends ActionBarActivity {

}

HeadlessSmsSendService：

public class HeadlessSmsSendService extends IntentService {
    public HeadlessSmsSendService() {
        super(HeadlessSmsSendService.class.getName());
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        throw new UnsupportedOperationException("Not yet implemented");
    }
}
