gradlew clean app:assembleDebug --profile

1、修改参数，加快build
org.gradle.jvmargs=-Xmx4608M -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
安卓：非发布版禁用fabric上报，修改jvmargs参数，使开发环境build时间降至2min以内

debug环境禁用fabric
非发布版本关闭Fabirc

android {
    buildTypes {
        debug {
          // Disable fabric build ID generation for debug builds
          ext.enableCrashlytics = false
          ...

2、配置不同的图标

配置不同app名称
遇到一个错误：


FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@label value=(@string/app_name_debug) from AndroidManifest.xml:86:9-37
    is also present at [:react-native-fetch-blob] AndroidManifest.xml:11:18-50 value=(@string/app_name).
    Suggestion: add 'tools:replace="android:label"' to <application> element at AndroidManifest.xml:80:5-324:19 to override.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

* Get more help at https://help.gradle.org

按照提示解决，解释：https://www.2cto.com/kf/201712/702939.html

3、配置不同applicationId
fileprovider 修改，https://www.jianshu.com/p/1afa7d4c0afd 提醒
FileHelp.java中使用父项目的BuildConf.applicationId

4、打jsbundle后生成的这个垃圾文件
D:\Git\pingtai\Portal\android\app\src\main\res\drawable-mdpi\js_commonview_echarts_tpl.html

5、android studio 中distributionUrl使用本地文件
D:\Git\pingtai\Portal\android\gradle\wrapper\gradle-wrapper.properties

distributionUrl.png

6、修改combile

7、开发环境使用比android studio 自带的【apply changes】更牛逼的【JRebel for Android】

1、安装Jrebel插件：https://zeroturnaround.com/software/jrebel-for-android/quick-start/#!/installation
2、激活帮助：http://blog.lanyus.com/archives/299.html

生成GUID：https://www.qvdv.com/tools/guid.html
我生成的：http://idea.lanyus.com/E086630D-638A-07A7-58D2-68ED4762D053
