Preface
This intern believes that for computer majors like us, the main thing is that the predecessors plant trees and the descendants can enjoy the shade. I have also read various documents on the Internet, searched for various error reports, and acted as a CV engineer. Under the documentation of predecessors, I have avoided a lot of detours and written a lot of code. It can be said that we enjoyed a lot of shade under the trees planted by our predecessors. I also wrote a document and shared a problem and task I encountered during my internship.
Some time ago, due to work problems, my boss gave me a task, how to call the back-end code on the uniapp front-end. After my study and use, I found that the principle is to use Android Studio to package Java code into an aar file that can be called by uniapp.
I am a back-end developer, but the knowledge here does not actually involve mainstream back-end Java development. This kind of operation is relatively niche, so many documents on the Internet are not detailed, so I compiled one myself.
In the process of searching for documents, I encountered many errors. Some of them even troubled me for several days. Because the documents on the Internet were not detailed and accurate, I summarized my development process and the errors I encountered in the process. and its solutions, organized into development documents. This development document has more detailed steps than other documents. Each step has a picture description, and it is organized in many ways, including error reports and very detailed solutions. I hope it can help everyone.
1. Development environment
1.JAVA environment jdk1.8
2.Android Studio download address: https://developer.android.google.cn/studio/index.html
3.App offline SDK download: https://nativesupport.dcloud.net.cn/AppDocs/download/android
4. HBuilderX download address: HBuilderX – Efficient Geek Techniques HBuilderX – Efficient Geek Techniques HBuilderX – Efficient Geek Techniques
5.Uniapp official documentation: Introduction | uni applet SDK
2. Unzip the SDK compressed package
3. Import the UniPlugin-Hello-AS project
(If an error is reported after opening, as shown below)
(If an error is reported, please modify the Gradle Version to the appropriate version)
(The picture below shows a successful demonstration)
4. Switch to project display
5. Provided demo file
Remove build.gradle plugin
Delete settings.gradle settings
Refresh the project
6. Create a new module and Add components in the build.gradle file
(If the build below in Android Studio still reports an error, for example)
(Solution: It is possible that the version configuration of the current project is incorrect:)
Modify it to
(After the error is resolved, add the plug-in)
7. Modify the test-module project file
plugins {
id 'com.android.library'
}
android {
namespace 'com.example.test_module'
compileSdkVersion 33
defaultConfig {
minSdkVersion 24
targetSdkVersion 28
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
consumerProguardFiles "consumer-rules.pro"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
repositories {
flatDir {

}
}

// androidTestImplementation 'androidx.test.ext:junit:1.1.5'
// androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
}
(Modifytest-module – AndroidManifest.xml)
8. Create a new UniTestModule.java
9. Compile the project and generate the arr package
(If the package file does not appear, you can refresh the project)
