In some cases, your computer may display an error message that the selected version of the Android device with a read-only file system could not be transferred. This problem can be caused by a number of reasons.
I am developing an SD card from my application to play songs. But when I add songs to the app, an error occurs
[2013-01-23 16:09:18 - ddms] Transfer error: file is write protected by the system [2013-01-23 16:09:18] Failed to force selection: read-only file system
I can adb push to the / sdcard / folder, but not to / system on my android device.
sudo adb stress lib / audio.primary.gmin.so system / lib / hw /'lib / audio.primary.gmin.so' cannot be copied to 'system / lib / hw / audio.primary.gmin.so': read-only file system

As a great Android developer, you can usually use the adb push command to copy files from your computer’s hard drive to your Android device. However, I just ran into a good problem where I couldn’t copy my own files to the “data” directory of the Android emulator, i.e. H. in its / data / data filesystem. When I tried to trace the file using this command:
Solution
The solution to this problem was to remount the emulator file system, since it is a read / write file system. I did it with a series of commands. In the following sequence, I ran command number one from my Mac / Unix operating system, and then the following commands were executed in the adb shell:
Back at the local filesystem prompt, I was able to copy my Instigate to the Android emulator filesystem using your current adb push command like this:
Apparently, you are ordering the file foo.jpg, which is located in my local Mac directory. The baud rate and number of bytes used indicate that the file was successfully copied to the emulator.
There may be other ways to copy files from your current local machine’s filesystem to the Android emulator’s filesystem, but I can confirm who (a) this approach works and (b) I created a “read-only filesystem” while I have followed this series of commands.
