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.

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

从Android备份到Desktop

打开命令行cmd并运行以下命令: adb backup -f C:\Intel\xxx。Ab -noapk你的。app.package。 不输入密码，点击备份我的数据。 确保不要保存在C根盘上。你可能会被拒绝。 这就是为什么我保存C:\英特尔。

来提取*。ab文件

点击这里下载:https://sourceforge.net/projects/adbextractor/ 解压缩下载的文件，并导航到解压缩的文件夹。 使用自己的文件名运行:java -jar abe.jar unpack c:\Intel\xxx英特尔ab c: \ \ xxx.tar

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 "

你可以像这样下载一个文件:

Adb执行run-as debug .app.package.name cat files/file.mp4 > file.mp4

在你下载之前，你可能不想看看你的App-Directory中的文件结构。要做到这一点，请按照上面THelper提到的步骤:

adb shell
run-as com.your.packagename 
cd files
ls -als .

Shahidul提到的Android-Studio方式(https://stackoverflow.com/a/44089388/1256697)也可以。对于那些在菜单中没有看到DeviceFile资源管理器选项的人:请确保在Android Studio中打开/ Android - directory。 例如，react-native用户在他们的Project-Folder中有这个和/ios-Directory在同一级别。
