組合的方式來命名的，用來明對應的客戶，比如：external_bluetooth_bluedroid_patchespatch都是要合入到客戶external/bluetooth/bluedroid/。一般情況下客戶的這些都會有g(shù)itproject，這時客戶只需要將該下的patch文件全部合入（gitam*.patch）SDK中即可。如果 沒有g(shù)itproject的話，那么需要客戶自己添加這部分到客戶的SDK中，方便后期客戶首先需要拷貝patch文件到指定的 ，比如對于external_bluetooth_bluedroid_patches 的patch文件，首先需要將這下面的patch文件全部拷貝到客戶的external\bluetooth\bluedroid
