You should read carefully this description on Android Developers, and make sure, that您应该仔细阅读 Android Developers 上的说明,并确保

),charhe only
),In the manifest file for the application you can set the android:installLocation value to 'preferExternal' - see the documentation here .在应用程序的清单文件中,您可以将 android:installLocation 值设置为“preferExternal” - 请参阅此处的文档。
There's no guarantee that the preference will be honored, but the SD card would be the default if you set preferExternal.无法保证首选项会得到尊重,但如果您设置了 preferExternal,SD 卡将是默认设置。
IF you have included android:installLocation="preferExternal" then after installing application go to settings->application->manage application from there you can move application to SD card.如果您已包含 android:installLocation="preferExternal" 则在将应用程序 go 安装到设置->应用程序->管理应用程序后,您可以将应用程序移动到 SD 卡。
