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.

你也可以尝试使用根资源管理器应用程序获取db。如果这不起作用，那么你可以试试这个:

打开cmd 改变目录，进入“平台工具” 类型为“adb shell” 苏 在设备上按“允许” chmod 777 /数据/数据/数据/数据/数据/ com.application。包/数据/数据/ com.application.package / * 在Eclipse中打开DDMS视图，然后从那里打开“FileExplorer”以获得所需的文件

在此之后，您应该能够浏览根设备上的文件。

使用eclipse中的文件资源管理器。Select Windows => Show View => Other…>文件资源管理器。

另一种方法是通过adb提取文件:

adb pull /system/data/data/<yourpackagename>/databases/<databasename> /sdcard

你可以复制这个db文件到eclipse资源管理器的某个地方(例如:sdcard或PC)，你可以使用sqlite访问和更新这个db文件。

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 "
