Then we found another more simple and effective way
1. From http://download.csdn.net/download/qq_ 38355313/12156696 download the common package you need
2. Directly put the required module into the LIBS folder
3. Add the original
implementation fileTree(include: ['*.jar'], dir: 'libs')
Change to
implementation fileTree(include: ['*.jar','*.aar'], dir: 'libs')
This problem can be solved, and the pro test is effective.

java.lang.RuntimeException: Error receiving broadcast Intent { act=com.***.servicecallback.content flg=0x10 (has extras) } in com.***.***.MainActivity$SocketMessageReceiver@b855039Later, I found out that it was caused by the following sentence:
Caused by: java.util.ConcurrentModificationExceptionLook at the reason again: if you modify vector and ArrayList at the same time during iteration, you will throw a Java. Util. Concurrent modificationexception.
The reason is that I use the list when I process data in onreceiver. When I traverse and iterate the query, I insert the data, which leads to the collapse of the list.

When referring to the above link articles or other articles, we still can’t solve the key error of Gaode
running the following two commands may solve the long-standing problem
cordova platform remove "platformName" // Remove the project platform
cordova platform add "platformName" // add device platform
Example:
cordova platform remove android // Remove Android project platform
cordova platform add android // add android device platformProblem: the installation of install depends on the APK with so library, so it can’t load so normally. Error: not found libc + +. So
for example: system. Loadlibrary (“inittest”);
analysis:
libandroid.so
libaaudio.so
libamidi.so
libbinder_ndk.so
libc.so
libcamera2ndk.so
libdl.so
libEGL.so
libGLESv1_CM.so
libGLESv2.so
libGLESv3.so
libicui18n.so
libicuuc.so
libjnigraphics.so
liblog.so
libmediandk.so
libm.so
libnativewindow.so
libneuralnetworks.so
libOpenMAXAL.so
libOpenSLES.so
libRS.so
libstdc++.so
libsync.so
libvulkan.so
libwebviewchromium_plat_support.so
libz.so
Scheme 1:
add libc + +. So to the white list
Scheme 2:
add the following configuration in the source code android.mk of libinittest.so:
LOCAL_NDK_STL_VARIANT := c++_static
LOCAL_SDK_VERSION := 8
Scheme 3:
copy libc + +. So to the same level directory of libinittest.so in your app to generate APK.
When an error occurs, do not suspect that the as is wrong! It’s just that there is an error in the newly compiled XML, not necessarily the file with the error prompt.
1. Execute file – & gt; Invalid cache/restart, recompile.
2. Check the latest XML file in the drawable folder for errors. Common errors are as follows:
I repeat
<?xml version=”1.0″ encoding=”utf-8″?& gt;
<?xml version=”1.0″ encoding=”utf-8″?& gt;
This error is due to the high version of cmake
In SDK manager, you can uninstall a higher version and download a lower version of cmake, such as version 3.6
Error prompt:
terms of settlement:
Project mode – & gt Idea folder – & gt; Gradle.xml, in & lt; GradleProjectSettings> Node, add this line of code:
If the above code is added or an error is reported, build – > After clean project is recompiled, the problem can be solved.

Solution:
Add swap partition
Today, I created a new small program project in wechat developer tool
but when I opened it, such a bug appeared
which made me feel very confused
Unhandled promise rejection TypeError: WebAssembly Instantiation: Argument 0 must be a buffer source or a WebAssembly.Module object
It was very uncomfortable
I went to the wechat developer community and asked
it turned out that the default version of the basic debugging library was too high, which led to an error
A simple solution
Click the details button in the upper right corner
and select local settings
to adjust the basic debugging library back to 2.14.4
**
Android studio cannot install the SDK when the software is installed
**
I don’t know what’s going on. Android’s AVD can’t be started. It’s stuck in the loading place all the time, indicating that it can’t respond. No matter it’s forced to shut down AVD or recreate one, it can’t be solved, so I decided to reload Android studio. However, when I uninstall Android and delete all the files and then install Android studio again, it always shows that the SDK has been installed and the project cannot be started because there is no SDK. As shown in the figure 
finally, with the help of the teacher, I can use the new Android studio again!! Tearful eyes
specific operation:
Problem description
For example, the screenshot is as follows, which is often empty above and incomplete below (recyclerview list) (blocked by the navigation bar at the bottom)
Problem solving ideas
After switching to another fragment, it is found that it is also lower than the whole, so it should be the whole setting problem, so the problem is located to activity_ Main.xml or mobile_ In navigation. XML, which is used to specify the newly created fragment, it turns out to be an activity_ Main.xml specifies mobile_ There’s a problem with navigation’s fragment.
Problem solving
At activity_ In main.xml
