emulator

只需加载kvm模块，同时启动命令上添加‘-qemu -enable-kvm’ 参数即可，启动命令：: emulator64-x86 -avd test -data userdata.img -qemu -m 2048 -enable-kvm

vm’ 参数即可，启动命令：: emulator64-x86 -avd test -data userdata.img -qemu -m 2048 -enable-kvm

其中的data如果没有指定，emulator好像每次都会初始化数据，也就是说重启之后，通过 adb安装的应用就没有了。

如果启动出现如下信息：: emulator: emulator window was out of view and was recentered 你可以添加’-scale auto’参数（取值范围0.1-3)，注意，非qemu参数都加在qemu前面。

另外avd文件存放在home/.android目录下。

你可以通过mksdcard创建sd镜像文件。

通过adb安装app和拷贝文件：

adb push localfile /sdcard/
adb install test.apk

启动sdk manager：: android sdk
启动avd manager：: android avd

具体的其他子命令可以help，主要是abd和android两个。

android sdk

About the version of Android SDK Build-tools, the answer is

By default, the Android SDK uses the most recent downloaded version of the Build Tools.

The [build] tools, such as aidl, aapt, dexdump, and dx, are typically called by the Android build tools or Android Development Tools (ADT), so you rarely need to invoke these tools directly. As a general rule, you should rely on the build tools or the ADT plugin to call them as needed. Source

Anyway, here is a synthesis of the differences between tools, platform-tools and build-tools:

Android SDK Tools Location: $ANDROID_HOME/tools Main tools: ant scripts (to build your APKs) and ddms (for debugging) Android SDK Platform-tools Location: $ANDROID_HOME/platform-tools Main tool: adb (to manage the state of an emulator or an Android device) Android SDK Build-tools Location: $ANDROID_HOME/build-tools/$VERSION/ Documentation Main tools: aapt (to generate R.java and unaligned, unsigned APKs), dx (to convert Java bytecode to Dalvik bytecode), and zipalign (to optimize your APKs)

编译过程是java->smali->dex, smali负责smali->dex, baksmali负责dex->smali, smali类汇编, 但是也可以修改.

一般如果你需要先获取apk, 然后通过apktool, 获取到apk的资源文件和smali, 然后可以直接通过smaliide(android studio插件)调试, 具体参考smalidea

你也能通过baksmali获取到smali代码, 修改之后smali重新打包

如果觉得smali很难懂, 也可以通过dex2jar把dex转换成jar包, 然后通过java反编译工具获取java代码, 当然这个反编译一般都是不完全的, 但是你也能完成apk的修改, 然后重新打包

android studio

启动bin/studio.sh 配置文件玩在~/.AndroidStudio1.5目录下, 调整jvm参数在该目录下的studio.vmoptions,

配置sdk: file->setting 配置project sdk: file->project structure下, platform settings -> sdks中选择”+“. 还需要配置project运行用的sdk, project setting -> project中选择project sdk和project language level

avd管理: tools -> android -> avd manager

debug

首先lsusb获取到id, 例如us 001 Device 004: ID 17ef:776d Lenovo

添加udev rules:

cat /etc/udev/rules.d/51-android.rules
DB your devices
SUBSYSTEM=="usb", ATTR{idVendor}=="17ef", ATTR{Product}=="776d", MODE="0666"

然后执行sudo adb kill-server && sudo adb start-server

接下来执行adb devices, 应该看到下面这样的行输出:

List of devices attached
813d4882        device

获取手机上的应用

adb shell pm list packages -f
adb pull -p PATH/base.apk OUTPUT.apk

安装到指定设备
adb -s "deviceIDfromlist" install path+apkName

apk

查看apk适配的架构

/apk/# build-tools/version/aapt dump badging ymatou-shop.apk
native-code: 'arm64-v8a' 'armeabi' 'armeabi-v7a' 'x86' 'x86_64'

migrate eclipse project to android studio

svn编码是gbk, 所以checkout代码出来的时候需要先修改LANG=zh_CN.gbk svn checkout file:///data/svn/android/zhijie/branches/vTest . svn checkout file:///data/svn/android/zhijie/branches/abs-library abs-library svn checkout file:///data/svn/android/zhijie/branches/sliding-library sliding-library

然后android studio直接import eclipse项目

接下来抛错误: Error:(12, 0) Error: NDK integration is deprecated in the current plugin. Consider trying the new experimental plugin. For details, see http://tools.android.com/tech-docs/new-build-system/gradle-experimental. Set “android.useDeprecatedNdk=true” in gradle.properties to continue using the current NDK integration. Open File

修改gradle.properties, 增加行android.useDeprecatedNdk=true

继续: ERROR: 9-patch image /home/tacy/workspace/android/zhijie_pay/zhijie_pay/src/main/res/drawable/navbar.9.png malformed

直接修改文件名为navbar.png(临时改法)

FAQ

Unable to install /home/admin/MyApp/app/build/outputs/apk/app-local-debug.apk

Step 1: Make sure your device is connected and then run adb devices. From the output, grab the device id H80xxxxxx. Step 2: Run react-native run-android –deviceId H80xxxxxx
