Even the test environment is slackware 12.0 + Android 1.5 R1 for Linux + JDK 1.6.0 _ 12, and ndk uses Android 1.5 ndk r1 (just decompress it directly, without installation ).

Android NDK development often has unexpected errors due to some factors. Many times debugging these errors is more complicated than debugging Java code. On the one hand, there are many causes of errors, on the other hand, NDK development involves writing C/C ++ code, which many programmers are not familiar. This blog will summarize s
