This is a simple app that can be used as a tutorial or reference benchmark
|
|
for the development of the DDMS native heap tracker feature. It contains 3
|
|
unique paths to allocate heap chunks:
|
|
|
|
1) Java_com_android_benchmark_moarram_MainActivity_add32ByteBlocksNative in
|
|
foo.c (libmoarram-foo.so). Each invocation will allocate 32 bytes.
|
|
2) Java_com_android_benchmark_moarram_MainActivity_add2MByteBlocksNative in
|
|
bar.c (libmoarram-bar.so). Each invocation will allocate 2M bytes.
|
|
3) Java_com_android_benchmark_moarram_MainActivity_addVariableSizedBlocksNative
|
|
in baz.c (libmoarram-baz.so). Each invocation will allocate 17 or 71 bytes,
|
|
depending on the active button in a radio group.
|
|
|
|
Each allocation can be freed by clicking the corresponding free button in the
|
|
UI.
|
|
|
|
NOTE 09/16/2013
|
|
A new feature is added to force a double free. Both debug libc and Valgrind can capture it.
