获取APK相关信息
前提#
Android中APK部分信息通过adb无法直接获取，但是可以通过Android中的ApplicationInfo接口进行获取。
获取内容#
- packageName：应用的包名，唯一标识每个APP
- appName：应用的名称，用户在界面上看到的名字
- isSystemApp：是否为系统应用，区分预装和用户安装
- launcherActivity：应用的启动Activity类名
- processName：应用运行的进程名称
- compileSdkVersion：编译时所用的SDK版本
- targetSdkVersion：目标适配的SDK版本
- icon：应用的图标数据

}

}
}使用方法#
第一步
安装APK
adb install -g app-debug.apk # 通过-g参数授予全部权限"第二步
启动APK
adb shell am start -n com.tt.appinfo/.MainActivity第三步
等待获取完成
adb shell cat /sdcard/Android/data/com.tt.appinfo/files/result.txt # 结果为1时，获取完成第四步
导出数据
adb pull /sdcard/Android/data/com.tt.appinfo/files/appInfo.db第五步
解析数据
可通过SQLite在线查看临时查看数据
python解析示例#
if __name__ == "__main__":
conn = sqlite3.connect('appInfo.db')
cursor = conn.cursor()
cursor.execute("SELECT _id, packageName, appName, isSystemApp, launcherActivity, processName, compileSdkVersion, targetSdkVersion, icon FROM apps")

isSystemApp = row[3]
launcherActivity = row[4]
processName = row[5]
compileSdkVersion = row[6]
targetSdkVersion = row[7]
icon = row[8]

}
if not os.path.exists("Icons"):
os.mkdir("Icons")
for package in appInfos.keys():

print(f"[{package}]compileSdkVersion: {compileSdkVersion}")
print(f"[{package}]targetSdkVersion: {targetSdkVersion}")
iconData = appInfos[package]['icon']
with open(f'Icons/{package}.png', 'wb') as f:
f.write(iconData)
print(f"{package} saved")C#解析示例#
