如何以 root 用户身份授予 .apk 权限？
how to give .apk permission as a root user?
我最近通过 buildozer 制作了一个 APK 文件。当我在 Ubuntu、windows 上打开此应用程序时它没问题，但它在 Android 上崩溃了。
所以我通过 adb logcat 调试并找到了崩溃的原因。
这是buildozer.spec

#[app@demo]
#title = My Application (demo)

# Then, invoke the command line with the "demo" profile:

这是因为权限被拒绝。
你可以看到底部的第二行告诉我权限被拒绝。
所以我创建了不需要根帐户的文件夹。但
它给了我这个日志。 （文件夹和文件显然存在）

那么这种情况有什么解决办法吗？
在 Android 上，您只有在应用的沙盒内进行写入的权限。没有主目录，您不能从根目录创建随机文件。您写入的目录由 context.getFilesDir() 定义。没有您可以假定的安全路径，因为应用程序的确切存储位置可能因设备和 API 级别而异。
我最近通过 buildozer 制作了一个 APK 文件。当我在 Ubuntu、windows 上打开此应用程序时它没问题，但它在 Android 上崩溃了。
所以我通过 adb logcat 调试并找到了崩溃的原因。
这是buildozer.spec

在 Android 上，您只有在应用的沙盒内进行写入的权限。没有主目录，您不能从根目录创建随机文件。您写入的目录由 context.getFilesDir() 定义。没有您可以假定的安全路径，因为应用程序的确切存储位置可能因设备和 API 级别而异。
