我的XML布局没有使用此错误消息进行渲染.我已经在使用Java 8了.

还使用Gradle中的最新构建工具.

android {
    compileSdkVersion 'android-N'
    buildToolsVersion 24.0.0 rc1
    ...
}

XML错误 -

我正在尝试API 22在将compileSdkVersion更新为N但无法执行此操作后在设备上运行APK .

compileSdkVersion 'android-N'
buildToolsVersion "24.0.0 rc1"

defaultConfig {
       minSdkVersion 14
       targetSdkVersion 'N'
}

这是原始图像.

Cam Scanner魔幻色彩效果.

我在图像上的过滤器.

我正在改变图像的对比度.

dst.convertTo(dst, -1, 2, 0);

然后使用高斯模糊进行平滑.

cv::GaussianBlur(dst,result,cv::Size(0,0),3);
cv::addWeighted(dst, 1.5, result, -0.5, 0, result);

我该怎么做才能对我的形象产生这种影响？

UPDATE

直方图均衡后 -

vector<Mat> channels;
Mat img_hist_equalized;
cvtColor(dst, img_hist_equalized, CV_BGR2YCrCb);
split(img_hist_equalized,channels);
equalizeHist(channels[0], channels[0]);
merge(channels,img_hist_equalized);
cvtColor(img_hist_equalized, img_hist_equalized, CV_YCrCb2BGR);

我正在订阅一个主题,这是我在Android中的应用程序版本.

FirebaseMessaging.getInstance().subscribeToTopic(APP_VERSION);

现在每次启动更新时,我都必须取消订阅旧版本并订阅新版本,因此如果我发送更新通知,则只有旧用户才能获得更新.相反,如果我只是否定一个版本就会很棒.

"condition": "!'2.1.1' in topics",

在FCM中是否存在类似的内容？

我已经有一个每天都会发出警报的警报FLAG_UPDATE_CURRENT.这是开发人员控制台的日志.

我正在使用Firebase 9.6.1.

更新:

public static void setAlarm(Context context, boolean isSet) {
  try {
     AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
     Intent intent = new Intent(context, AlarmReceiver.class);

     boolean isWorking = (PendingIntent.getBroadcast(context,
                SettingsActivity.REQUEST_CODE, intent, PendingIntent.FLAG_NO_CREATE) != null); …

这是我如何在FrameLayout中动态添加地图.

new Handler().postDelayed(() -> {
  if (isAdded()) {
   new Thread(() -> {
    try {
     SupportMapFragment mf = SupportMapFragment.newInstance();
     getChildFragmentManager().beginTransaction()
      .replace(R.id.view_map, mf)
      .commit();
     mActivity.runOnUiThread(() -> mf.getMapAsync(this));
    } catch (Exception ignored) {}
   }).start();
  }
 }, 100);

它工作正常但在某些情况下应用程序崩溃了Resources$NotFoundException.这是崩溃日志.

我在Google Pixel上测试Google Map,运行最新版本的Android Pie.

将PDF文件转换.tiff为非常简单的文件

convert -depth 4 -density 300 -background white +matte eng.arial.pdf eng.arial.tiff

然后训练tesseract的.tiff文件 -

tesseract eng.arial.tiff eng.arial batch.nochop makebox

然后将.tiff文件输入tesseract -

tesseract eng.arial.tiff eng.arial.box nobatch box.train .stderr

检测使用的字符集 -

unicharset_extractor *.box 

但是我收到了这个错误 -

unicharset_extractor:./.libs/lt-unicharset_extractor.c:233: FATAL: couldn't find unicharset_extractor.

而且它也发生了mftraining和combine_tessdata为好.

UPDATE

在单个文件夹文件中运行unicharset_extractor仍然无法正常工作.

它不仅有这个命令,还有和mftraining,cntraining和combine_tessdata.

我正在添加一个TextView具有属性的浮动窗口android:textisselectable.

mWindowManager.addView(textView, params);

Eveything工作正常,但我无法在长按时复制文本.奇怪的是,它在Galaxy Tab中运行良好,但在我拥有的任何其他5英寸手机上都没有.

我使用的是Google Places API.但是,如果不实现其余的API,我找不到减少请求数量的方法.

    try {
        Intent intent = new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
                .setFilter(new AutocompleteFilter.Builder()
                        .setTypeFilter(AutocompleteFilter.TYPE_FILTER_ADDRESS).build())
                .build(mActivity);
        startActivityForResult(intent, REQUEST_CODE);
    } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException e) {
    }
