Question

我尝试使用此功能删除手机中的所有短信：

 public void wipeOutAllSMS(Context context) {
    try {

        int rowsDeleted = 0;

        Uri uriSms = Uri.parse("content://sms/inbox");
        Cursor c = context.getContentResolver().query(uriSms, new String[]{"_id", "thread_id", "address", "person", "date", "body"}, "read=0", null, null);

        if (c != null && c.moveToFirst()) {
            do {
                long id = c.getLong(0);
                long threadId = c.getLong(1);
                String address = c.getString(2);
                String body = c.getString(5);
                String date = c.getString(3);

                // mLogger.logInfo("Deleting SMS with id: " + threadId);
                rowsDeleted += context.getContentResolver().delete(Uri.parse("content://sms/" + id), "date=?", new String[]{c.getString(4)});

                Log.i("Deleting_SMS", "Delete success for: " + address + ", message = " + body);

            } while (c.moveToNext());
        }

        Log.i("Deleting_SMS", "rows deleted: " + rowsDeleted);

    } catch (Exception e) {
        Log.e("Deleting_SMS", e.toString());
    }
}

不幸的是，“rows_deleted”始终为0.它不会删除单个短信。

我已将我的清单添加到以下内容中：

权限：

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

其他事项是为了能够选择我的应用作为默认的短信读取器：

<!--The following things are needed for this app to became the default sms app in order to have the ability to delete an sms. -->

        <!-- BroadcastReceiver that listens for incoming SMS messages -->
        <receiver
            android:name=".android.broadcast.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=".android.broadcast.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>

        <!-- This one needs too-->


        <!-- Service that delivers messages from the phone "quick response" -->
        <service android:name=".android.broadcast.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>

我还要求app start的权限，我最终接受：

if (!PermissionHelper.isPermissionGranted(this, Manifest.permission.SEND_SMS) || !PermissionHelper.isPermissionGranted(this, Manifest.permission.READ_SMS)) {
            PermissionHelper.requestPermission(this,
                    new String[]{
                    Manifest.permission.SEND_SMS,
                    Manifest.permission.READ_SMS
            });
}

（ Manifest.permisson 中不存在 WRITE_SMS 权限，所以我无法提出要求。）

我还将设备上的默认短信读取器设置为我的应用。但是我无法删除单个短信。

如果可以，请帮忙。

我使用android Marshmallow，没有抛出异常。

如果您是默认应用，则可以像这样删除。

  Uri.Builder builder;
  builder = Sms.CONTENT_URI.buildUpon();
  //builder.appendEncodedPath(getSms_id());
  builder.appendEncodedPath("your SMS ID here");
  Uri uri = builder.build();
  context.getContentResolver().delete(uri, null, null);

无法以编程方式删除SMS（默认SMS应用程序集）
