Here is a simple method to solve error: NO ST-LINK detected/ST-LINK USB communication
Solution:
① download and install STLINK driver
② update STLINK firmware
③Find stlink_winusb_uninstall.bat in your keil5 installation directory>ARM>STLink>USBDriver directory and click to execute it (i.e. uninstall first), then execute stlink_winusb_install.bat again (i.e. reinstall)
As long as it is recorded on the screen, it is difficult to report errors. The common causes and solutions are summarized as follows:
1. Determine the storage permission. Note that Android 10, 11, 12, etc. the storage permission policy of Android has changed. Set the output path to ensure that it is under the path with read-write permission
File file=new File(getExternalFilesDir("")+"/Ansen_");
if(!file.exists()){
file.mkdirs();
}
//Set the video output path
mMediaRecorder.setOutputFile(file.getAbsolutePath() + "/Ansen_" + curTime + ".mp4");2. Correctly set the size of the recording screen, here note that this size is not necessarily the screen size, through the following method is not necessarily the same as the actual resolution, such as a plus phone, originally 1920 * 1080, in fact, through the following measurement results are not, this will require developers to get through the Camera.
//Set the video size
mMediaRecorder.setVideoSize(ScreenUtils.getScreenWidth(this), ScreenUtils.getScreenHeight(this));Conventional method for obtaining the size of mobile phone (not necessarily accurate, inconsistent with the recording screen):
/**
* Get the width of the screen px
*/
public static int getScreenWidth(Context context) {
WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
DisplayMetrics outMetrics = new DisplayMetrics();
windowManager.getDefaultDisplay().getMetrics(outMetrics);
return outMetrics.widthPixels;
}
/**
* Get the width of the screen px
*/
public static int getScreenHeight(Context context) {
WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
DisplayMetrics outMetrics = new DisplayMetrics();
windowManager.getDefaultDisplay().getMetrics(outMetrics);
return outMetrics.heightPixels;
}
To get the resolution supported by the camera, just select a group from the following.
Camera camera = Camera.open();
Parameters parameters = camera.getParameters();
List<Size> supportedPreviewSizes = parameters.getSupportedPreviewSizes();
for (int i = 0; i < supportedPreviewSizes.size(); i++) {
supportedPreviewSizes.get(i).width;
supportedPreviewSizes.get(i).height;
}
List<Size> supportedPictureSizes = parameters.getSupportedPictureSizes();
for (int i = 0; i < supportedPictureSizes.size(); i++) {
supportedPictureSizes.get(i).widt;
supportedPictureSizes.get(i).height;
}3. Determine the setting sequence, which will affect
setAudioSource()
setVideoSource()
setOutputFormat()
setAudioEncoder()
setVideoEncoder()
setVideoSize()
setVideoFrameRate()
setOutputFile()
setVideoEncodingBitRate()
prepare()
start()

According to the error message The minCompileSdk (31) specified, the final sdk needs to be version 31, but our current sdk version is 30, which is greater than this version, so we need to modify the following configuration to 31
android {
compileSdkVersion 31
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).

}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.

From the error message, it is said that the version of kotlin is wrong, and a specific solution is given
Your project requires a newer version of the Kotlin Gradle plugin. │
│ Find the latest version on https://kotlinlang.org/docs/gradle.html#plugin-and-versions, then │
│ update D:\javadeveloping\Android\workspace\kqjhq_app\android\build.gradle: │
│ ext.kotlin_version = '<latest-version>'
You need an up-to-date plugin named kotlin gradle, Find the recent version in https://kotlinlang.org/docs/gradle.html#plugin-and-versions and update the the latest-version value in ext.kotlin_version = ‘’ of the D:\javadeveloping\Android\workspace\kqjhq_app\android\build.gradle file.
after opening the web page, we found that the latest version is 1.6.10, while our previous version is 1.3.5:
just change to 1.6.10 and package normally
When using angular12 (version 12.0.3) to develop a project, the debugging will run normally, but an error message will appear when calling ng build to publish.
Tip: index HTML generation failed undefined:6:720366 missing ‘}’
Or: index HTML generation failed Undefined: 6:720366 missing ‘:’ etc.
The solution is to modify the angular.json configuration file, Add an optimization node under the build -> configurations ->production node:
"optimization": {
"scripts": true,
"fonts": {
"inline": true
},
"styles": {
"minify": true,
"inlineCritical": false
}
}The complete node path is:
{

The complete error information is shown in the figure below:
According to the online method, I tried export pythonhttsverify = 0 and still reported an error
Try the following method to set the environment variable SSL_CERT_Dir, problem solving, you might as well try it.
$ sudo update-ca-certificates --fresh
$ export SSL_CERT_DIR=/etc/ssl/certs

<name>Restlet repository</name>
<url>https://maven.restlet.talend.com</url>

</repositories>Problem: when I write my own code to debug the manipulator, there is a problem after the rosrun node, as shown in the figure below
Solution: add the following two sentences at the entrance of the main function
ros::NodeHandle nh;
ros::AsyncSpinner spinner(1);
The reason is that movegroupinterface depends on ROS spinning, so just add the above two sentences before movegroupinterface

It seems that the error message may be the problem of dependent packages
I just added dependent packages:
implementation 'com.github.bumptech.glide:glide:4.7.1'
This dependency package version 4.7.1 may refer to the androidx library, 4.7.1 back to which version (Just google to find the corresponding version) to refer to the android library, there should be no problem
