一： build.gradle
1.

    repositories {        jcenter()    }

>>

    repositories {        google()        jcenter()    }

2. 

    dependencies {        //noinspection GradleDependency        classpath 'com.android.tools.build:gradle:3.3.2'        classpath 'com.getkeepsafe.dexcount:dexcount-gradle-plugin:0.3.0'    }

>>

    dependencies {        //noinspection GradleDependency        classpath 'com.android.tools.build:gradle:3.3.2'        classpath 'com.getkeepsafe.dexcount:dexcount-gradle-plugin:0.6.4'    }

3.

allprojects {    repositories {        jcenter()....

>>

allprojects {    repositories {        google()        maven {            url 'https://maven.google.com'        }...

二：app/build.gradle
1. 

    applicationVariants.all { variant ->        variant.outputs.each { output ->            output.outputFile = new File(                    output.outputFile.parent + "/${variant.buildType.name}",                    "osc-android-${variant.versionName}-${variant.productFlavors[0].name}.apk".toLowerCase())        }    }

>>

    applicationVariants.all { variant ->        variant.outputs.all { output ->            def outputFile = output.outputFile            def fileName            if (outputFile != null && outputFile.name.endsWith('.apk')) {                if (variant.buildType.name.equals('release')) {                    fileName = "osc-android_release_v${defaultConfig.versionName}.apk"                } else if (variant.buildType.name.equals('debug')) {                    fileName = "osc-android_debug_v${defaultConfig.versionName}.apk"                }                outputFileName = fileName            }        }    }

2. compile -》 implementation
3. testCompile -》 testImplementation 
4. androidTestCompile -》 androidTestImplementation
5. defaultconfig标签下增加
        flavorDimensions "default"
        //解决Annotation processors must be explicitly declared now问题--20181019
        javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }
6. 

        ndk {            //设置支持的SO库架构            abiFilters 'armeabi' //, 'arm64-v7a', 'x86' , 'x86_64','arm64-v8a',        }

>>

ndk {            //设置支持的SO库架构            //abiFilters 'armeabi' //, 'arm64-v7a', 'x86' , 'x86_64','arm64-v8a',abiFilters 'x86', 'x86_64', 'armeabi-v7a','arm64-v8a'        }

三： open/build.gradle
1. 

dependencies {    compile fileTree(include: ['*.jar'], dir: 'libs')    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    testCompile 'junit:junit:4.12'    compile "com.android.support:support-v4:$rootProject.ext.supportVersion"        compile files('libs/open_sdk_r5781.jar')}

>>

dependencies {    api fileTree(include: ['*.jar'], dir: 'libs')    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    testImplementation 'junit:junit:4.12'    implementation "com.android.support:support-v4:$rootProject.ext.supportVersion"        api files('libs/open_sdk_r5781.jar')}

四：app/src/main/res/values/theme.xml
