python調用aapt工具直接獲取包名和tagertSdkversion

背景：

每次海外游戲上架都需要符合google的上架規則，其中適配方面tagetSdkversion有硬性要求，比如需要適配安卓q就需要tagetSdkversion達到28，水平太渣的我每次調用aapt工具都需要在cmd中輸入大量指令，且aapt dump baging指令會返回大量相關以及無關信息，為了方便過濾相應信息，編寫代碼直接獲取相關信息，排除無關信息

以劍網3指尖江湖的安裝包為例

若直接使用aapt工具，返回信息如下圖所示

思路：

re模塊使用正則表達式過濾無關信息，os模塊調用環境變量中的ANDROID_HOME，subprocess創建一個新的進程讓其執行另外的程序，並與它進行通信，獲取標准的輸入、標准輸出、標准錯誤以及返回碼等。 

我們實際需要的相關信息紅框部分，其余都是無關信息，所以需要re模塊去過濾出相關信息

代碼：

    def __init__(self, apk_path):
        self.apkPath = apk_path
        self.aapt_path = self.get_aapt()

            for path, subdir, files in os.walk(root_dir):
                if "aapt.exe" in files:
                    return os.path.join(path, "aapt.exe")
        else:
            return "ANDROID_HOME not exist"

if __name__ == '__main__':
    apk_info = ApkInfo(r"apk文件路徑")
    print("Activity:%s"%apk_info.get_apk_activity())
    print("apkName:%s"%apk_info.get_apk_base_info())
    print("sdkVersion:%s"%apk_info.get_apk_sdkVersion())
    print("targetSdkVersion:%s"%apk_info.get_apk_targetSdkVersion())

 在pycharm中直接運行，結果如下圖所示
