You can package libs and. so files by writing android multi-channel packaging tools.

When uploading an android app, you need to separate each channel. A channel id is usually changed in the configuration file. If there are multiple channels, manual modification and apk generation will be very troublesome and increase the error probability.

Here is a packaging tool class. The Internet is similar. I optimized it based on it, especially the so file packaging. A small command is useless.

The umeng used in our project is used as a statistical analysis tool. umeng needs to modify

<Meta-data android: name = "UMENG_CHANNEL" android: value = "@ string/channel_name"/> value.

This value is stored in strings. xml <string name = "channel_name"> app_channel </string>. Therefore, you only need to modify app_channel during compilation.

The following is a tool class. Run it directly.
