SQLlite数据库存储在用户的手机，它隐藏在路径下:

/Data/Data/com.companyname.AppName/File/

你有两个选择:

你可以根你的手机，这样你就可以查看你的隐藏 db4文件 这不是解决方案，而是一种变通办法。为什么不直接创建测试呢 使用“select”语句在其中显示数据库表的页面。

在未根的Android 5.0+设备上从可调试应用程序文件夹(例如/data/data/package.name/databases/file)中提取文件最简单的方法(只是一个简单的步骤)是使用以下命令:

adb exec-out run-as package.name cat databases/file > file

adb backup didn't work for me, so here's what I did (Xiaomi Redmi Note 4X, Android 6.0): 1. Go to Settings > Additional Settings > Backup & reset > Local backups. 2. Tap 'Back up' on the bottom of the screen. 3. Uncheck 'System' and 'Apps' checkmarks. 4. Tap detail disclosure button on the right of the 'Apps' cell to navigate to app selection screen. 5. Select the desired app and tap OK. 6. After the backup was completed, the actual file need to be located somehow. Mine could be found at /MIUI/backup/AllBackup/_FOLDER_NAMED_AFTER_BACKUP_CREATION_DATE_. 7. Then I followed the steps from this answer by RonTLV to actually convert the backup file (.bak in my case) to tar (duplicating from the original answer): " a) Go here and download: https://sourceforge.net/projects/adbextractor/ b) Extract the downloaded file and navigate to folder where you extracted. c) run this with your own file names: java -jar abe.jar unpack c:\Intel\xxx.ab c:\Intel\xxx.tar "

要做到以上任何一项(即从手机本身访问受保护的文件夹)，你仍然需要root。(这包括更改/data文件夹的挂载权限并访问它)

如果没有root，除了通过代码从应用程序内部读取外，直接访问/数据是不可能的。所以你可以试着把那个文件复制到sdcard或者其他可以访问的地方，然后，你就可以正常访问它了。

如果您使用的是开发人员设备，那么root不会使您的保修失效。对不起，我没有别的办法了。

直接在手机上访问这些文件很困难，但你可以将它们复制到你的电脑上，在那里你可以做任何你想做的事情。 没有根你有两个选择:

If the application is debuggable you can use the run-as command in adb shell adb shell run-as com.your.packagename cp /data/data/com.your.packagename/ Alternatively you can use Android's backup function. adb backup -noapk com.your.packagename You will now be prompted to 'unlock your device and confirm the backup operation'. It's best NOT to provide a password, otherwise it becomes more difficult to read the data. Just click on 'backup my data'. The resulting 'backup.ab' file on your computer contains all application data in android backup format. Basically it's a compressed tar file. This page explains how you can use OpenSSL's zlib command to uncompress it. You can use the adb restore backup.db command to restore the backup.
