我知道我有一个可调试的APK，我在手机上运行它，基于以下输出显示该文件被推送到我的手机：
sansari@ubuntu:~/AndroidStudioProjects/Usetbt/app$ ls
app.iml build build.gradle libs proguard-rules.pro src
sansari@ubuntu:~/AndroidStudioProjects/Usetbt/app$ adb install ./build/outputs/apk/app-debug.apk
693 KB/s (1092843 bytes in 1.537s)
pkg: /data/local/tmp/app-debug.apk
Success
但是当我运行GDB时，它会抱怨apk无法调试：
sansari@ubuntu:~/AndroidStudioProjects/Usetbt/app/src/main$ ndk-gdb --verbose

ERROR: Package com.example.sansari.usetbt is not debuggable ! You can fix that in two ways:
- Rebuilt with the NDK_DEBUG=1 option when calling 'ndk-build'.
- Modify your manifest to set android:debuggable attribute to "true",
then rebuild normally.
After one of these, re-install to the device!
我认为这是因为我从项目的/ main目录调用gdb，这是GDB似乎开始运行的唯一地方。并且它不具有可调试文件的可见性，该文件不受文件结构的不同分支的影响。请参阅以下内容：
../../
├── app.iml
├── build
│ ├── outputs
│ │ ├── apk
│ │ │ ├── app-debug.apk
│ │ │ └── app-debug-unaligned.apk
│ │ └── logs
│ │ └── manifest-merger-debug-report.txt
└── src
├── main

所以问题是如何运行GDB，它应该从项目根运行并以某种方式告诉它使用可调试文件？
