粗略有几种方法
1. One way to do this is with freeware Android Injector. http://www.harmonyhollow.net/android_injector.shtml
2. You can use the Android Debug Bridge (adb) to install applications. You need to connect your phone to your computer via USB and possess the .apk file to do it. Check out the Installing an Application section on that page. ADB requires the Android SDK. So you must first install that.
3. upload the .apk on your computer to dropbox, open dropbox app on android, click file, install. No need to connect the phone to the computer.
3. 我试过很好用。 1, 2 还没试过。
