如何以编程方式删除android中特定地址的已发送/已发送/未发送的短信

Question

我正在使用下面的代码来删除 SMS，它在 android 版本 5.0.2 上运行良好，但在 6.0.1 上无法运行。该代码是为 API-22(targetSdkVersion) 构建的，因为我想避免应用程序中的运行时权限模型。

public static  void deleteSTMessage()
{
    String SMS_INBOX= "content://sms/";
    Uri inboxURI = Uri.parse(SMS_INBOX);
    Cursor c = STApplication.getContext().getContentResolver().query(inboxURI, new String[] { "_id", "thread_id", "address", "person",
            "date", "body" }, null, null, null);
    try {

        while (c.moveToNext()) {
            try {
                if (c != null && c.moveToFirst()) {
                    do {
                        String address=c.getString(2);
                        String id= c.getString(0);
                        long threadId = c.getLong(1);
                       // String stringFromBase = c.getString(5);
                        try
                        {
                            if(address.equalsIgnoreCase(AppConfig.DESTINATION_ADDRESS))
                            {
                                int deltedrowcount = STApplication.getContext().getContentResolver().delete(Uri.parse("content://sms/" + id), null, null);
                                FileLog.v(TAG, "- ST Client SMS has Deleted successfully " );
                            }
                        }catch (Exception e){
                               FileLog.v(TAG,"- Exception in deleting SMS  "+e.getLocalizedMessage());
                        }

                    } while (c.moveToNext());
                }
            } catch (Exception e) {
                FileLog.v(TAG,"- Exception in deleting SMS "+e.getLocalizedMessage());
            }
        }
    }catch (Exception e){
        FileLog.v(TAG,"- Exception in deleting SMS "+e.getLocalizedMessage());
    }finally {
        c.close();
    }
}

它允许我阅读短信，但是当我试图通过代码删除短信受影响的行数时返回 0。经过一番谷歌搜索后，我从link 了解到，从 API-19 开始，除非您将应用程序创建为默认 SMS 应用程序，否则您无法正常使用 SMS，但我不想创建成熟的 SMS 默认 SMS 客户端，如我的应用没有任何用户交互。

我也有疑问，如果从 KITKAT 删除 SMS 对棒棒糖起作用，SMS API 发生了变化。

我只需要在 ANDROID-M 中从所有已发送/收件箱/未发送的地方删除特定收件人电话号码的短信 如果你们看不懂我的英语，请帮助我并原谅我 提前致谢

幸运的是，我通过使用 Java 反射解决了我的问题，因为我浏览了 android 框架源代码并意识到要删除 SMS，我们需要将 AppOpsManager 类的 MODE_ALLOWED 变量设置为 true(AppOpsManager.MODE_ALLOWED= true)，因为我使用了 Java反射并创建一个类SmsWriteOpUtil.java，其代码为

public class SmsWriteOpUtil {
private static final int OP_WRITE_SMS = 15;

public static boolean isWriteEnabled(Context context) {
    int uid = getUid(context);
    Object opRes = checkOp(context, OP_WRITE_SMS, uid);

    if (opRes instanceof Integer) {
        return (Integer) opRes == AppOpsManager.MODE_ALLOWED;
    }
    return false;
}

public static boolean setWriteEnabled(Context context, boolean enabled) {
    int uid = getUid(context);
    int mode = enabled ?
            AppOpsManager.MODE_ALLOWED : AppOpsManager.MODE_IGNORED;

    return setMode(context, OP_WRITE_SMS, uid, mode);
}

private static Object checkOp(Context context, int code, int uid) {
    AppOpsManager appOpsManager =
            (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
    Class appOpsManagerClass = appOpsManager.getClass();

    try {
        Class[] types = new Class[3];
        types[0] = Integer.TYPE;
        types[1] = Integer.TYPE;
        types[2] = String.class;
        Method checkOpMethod =
                appOpsManagerClass.getMethod("checkOp", types);

        Object[] args = new Object[3];
        args[0] = Integer.valueOf(code);
        args[1] = Integer.valueOf(uid);
        args[2] = context.getPackageName();
        Object result = checkOpMethod.invoke(appOpsManager, args);

        return result;
    }
    catch (NoSuchMethodException e) {
        e.printStackTrace();
    }
    catch (InvocationTargetException e) {
        e.printStackTrace();
    }
    catch (IllegalAccessException e) {
        e.printStackTrace();
    }
    return null;
}

private static boolean setMode(Context context, int code,
                               int uid, int mode) {
    AppOpsManager appOpsManager =
            (AppOpsManager) context.getSystemService(Context.APP_OPS_SERVICE);
    Class appOpsManagerClass = appOpsManager.getClass();

    try {
        Class[] types = new Class[4];
        types[0] = Integer.TYPE;
        types[1] = Integer.TYPE;
        types[2] = String.class;
        types[3] = Integer.TYPE;
        Method setModeMethod =
                appOpsManagerClass.getMethod("setMode", types);

        Object[] args = new Object[4];
        args[0] = Integer.valueOf(code);
        args[1] = Integer.valueOf(uid);
        args[2] = context.getPackageName();
        args[3] = Integer.valueOf(mode);
        setModeMethod.invoke(appOpsManager, args);

        return true;
    }
    catch (NoSuchMethodException e) {
        e.printStackTrace();
    }
    catch (InvocationTargetException e) {
        e.printStackTrace();
    }
    catch (IllegalAccessException e) {
        e.printStackTrace();
    }
    return false;
}

private static int getUid(Context context) {
    try {
        int uid = context.getPackageManager()
                .getApplicationInfo(context.getPackageName(), PackageManager.GET_ACTIVITIES).uid;

        return uid;
    }
    catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
        return 0;
    }
}

}

并在 manifest.xml 中添加以下权限

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

而我修改的deleteSTMessage()方法代码是

public static void deleteSTMessage() {
    Uri uri= Telephony.Sms.CONTENT_URI;
    Cursor c = STApplication.getContext().getContentResolver().query(uri, new String[]{"_id", "thread_id", "address", "person",
            "date", "body"}, null, null, null);
    try {

        while (c.moveToNext()) {
            try {
                if (c != null && c.moveToFirst()) {
                    do {
                        String address = c.getString(2);
                        String id = c.getString(0);
                        long threadId = c.getLong(1);
                        String body = c.getString(5);
                        //FileLog.v(LOG_TAG , " address: "+address + " body: "+body + " threadId: "+ threadId + " id: "+id );
                        try {
                            if(!SmsWriteOpUtil.isWriteEnabled(STApplication.getContext())) {
                                boolean canWriteSms = SmsWriteOpUtil.setWriteEnabled(STApplication.getContext(), true);
                                FileLog.v(LOG_TAG, " canWriteSms: "+canWriteSms);

                            }
                            if ( address.replaceAll("\\s","").contains(Constants.DESTINATION_ADDRESS)) {
                                    int deltedrowcount = STApplication.getContext().getContentResolver().delete(uri, "thread_id = "+threadId, null);
                                //int deltedrowcount = STApplication.getContext().getContentResolver().delete(Uri.parse("content://sms/" + id), null, null);
                                if(deltedrowcount!=0){
                                    FileLog.v(LOG_TAG, " !!! ST Client SMS has Deleted successfully " + deltedrowcount);
                                }

                            }
                        } catch (Exception e) {
                            FileLog.v(LOG_TAG, " !!!  Exception in deleting SMS  " + FileLog.getStackTraceString(e));
                        }

                    } while (c.moveToNext());
                }
            } catch (Exception e) {
                FileLog.v(LOG_TAG, " !!! Exception in deleting SMS " + FileLog.getStackTraceString(e));
            }
        }
    } catch (Exception e) {
        FileLog.v(LOG_TAG, " !!!! Exception in deleting SMS " + FileLog.getStackTraceString(e));
    } finally {
        c.close();
    }
}

根据上面在我的问题中的讨论，我正在创建系统应用程序，因此它对我来说非常有效，我测试此代码以用于正常应用程序，但它失败了。

希望这段代码对开发者社区有所帮助，因为我花了很多天时间。 在此先感谢
