Split APK简介和手动安装方法

[xiaokaixuan]

简介

Split APK是Google为解决65536上限，以及APK安装包越来越大等问题，在Android L中引入的机制。 Split APK可以将一个庞大的APK，按屏幕密度，ABI等形式拆分成多个独立的APK，在应用程序更新时，不必下载整个APK，只需单独下载某个模块即可安装更新。 Split APK将原来一个APK中多个模块共享同一份资源的模型分离成多个APK使用各自的资源，并且可以继承Base APK中的资源，多个APK有相同的data，cache目录，多个dex文件，相同的进程，在Settings.apk中只显示一个APK，并且使用相同的包名。

安装

命令安装

adb shell pm install-create # create a session (1237281889)
# Success：created install session [1237281889]
adb shell pm install-write session (1237281889) baseapk (base.apk) apk_path (/data/local/tmp/FeatureSplitBase.apk)
adb shell pm install-write session (1237281889) splitapk (base1.apk) apk_path (/data/local/tmp/FeatureSplit1.apk)
adb shell pm install-commit session (1237281889)

模块安装 Base APK必须已经安装到手机中

adb shell pm install-create -r –p installed_packagename (com.android.test.split.feature)
adb shell pm install-write session splitapk (base1.apk) apk_path (/data/local/tmp/FeatureSplit1.apk)
adb shell pm install-commit session

命令示例

adb shell pm install-create
# Success：created install session [1237281889]
adb shell pm install-write  1237281889 base.apk /data/local/tmp/FeatureSplitBase.apk
adb shell pm install-write  1237281889 base1.apk /data/local/tmp/FeatureSplit1.apk
adb shell pm install-write  1237281889 base2.apk /data/local/tmp/FeatureSplit2.apk
adb shell pm install-commit 1237281889
