With a new system, a new computer, and a previous development environment, everything has to be done again.
A. First, some problems occurred when installing apt: Because my eclipse version is newer, some errors occurred when installing apt. I forgot the details, as if I remembered "core. *. . Online tutorials are complicated and fail to solve my problem many times. My final solution is:
Help-> check updates to update the plug-in library it should have.
B. The following problem occurs when creating the simulator:
Error: failed to create the SD card.
Error: failed to create sdcard In the AVD folder.
Solution:
There are two reasons
1. Set the tools permission under the android SDK to the executable permission.
2. There is no reason to install the ia32-libs, In the 64-bit ubantu is not allowed to run the 32-bit program, unless installed this. Use sudo apt-Get install ia32-libs
C. When creating a simulator (because I want to experiment quickly, I downloaded some basic toolkit and 4.0 packages, but other versions are not available), I cannot create a new simulator: unable to find a' userdata. IMG 'file for Abi armeabi to copy into the AVD folder .....
The solution is that the package of the arm Eabi v7a system image is not downloaded by default, so you can download the package in the android SDK manager.
