问题描述：使用的是android studio版本2.2.1，在用模拟器调试apk的时候需要将比较大的文件放置在根目录便于读取，通过Tools->Android->Android Device Monitor打开了DDMS，找到了mnt->sdcard，然后选择文件，点击push、pull文件，可是总是报错

Ask and answer your own questions. I talked to a friend this afternoon and finally found the problem.
The files should be placed in the path:
storage->sdcard. Of course, it will be very troublesome to push files in batches. It is best to compress the files and then push them. However, there is no file manager in the simulator, so it is best to do it yourself. Next, I used the Es file browser to download it, drag it directly into the simulator, and it will be installed automatically. It is very convenient, and it is also strange. I wanted to install an apk for file decompression, but it didn't work after several attempts. . . . Someone who knows why, please tell me. Later, I remembered that Es seems to have its own decompression function, and then I tried it, and it worked (but an error will be reported when copying the js file, and it took a few attempts).In addition, I am a newbie, and while I am learning Android by myself, I feel that the emulator of Android Studio is getting worse and worse. When I first installed version 2.0, it had various lags, but now it is comparable to a real machine. @xialomg It’s not that I don’t want to use a real phone, but my phone’s android version is 6.0+, and the project requires 4.4.4.
Additional picture:
The emulator may not have enough space. Try using emulator -partition-size 1024 @myavd. If it doesn’t work, use a real machine
1.Open shell
2. Enter the root directory
3. Get the full path to the root directory
4.push file to the root directory
