crashlog:Android 应用程序崩溃日志保存到文件

#crashlog Android app crash logs to a file. 안드로이드 앱에서 Crash 로그를 파일로 기록하는 코드입니다. 기존 Android에서는 개발자 모드에서만 crash 로그를 기록합니다. crashlog는 앱에 libcrashlog.so를 동적로딩하면, 앱에서 지정한 디렉토리로 crash log를 파일로 생성합니다. ![ViewPagerIndicator Sample Screenshots][1] ##edit $vi local.properties ``` sdk.dir=<your sdk path> ndk.dir=<your ndk path> NDKBUILD=ndk-build (linux, mac) or ndk-build.cmd (windows) ``` ##Complie ``` $make or ./gradlew assemble ``` 하면 컴파일을 합니다. ``` ls app/build/outputs/apk/ app-debug.apk app-debug-unaligned.apk app-release-unsigned.apk manifest-merger-debug-report.txt manifest-merger-release-report.txt ``` apk 파일이 생성됩다. #디렉토리및 앱 버전정보 수정 ``` vi example/android/src/com/example/crashlog/CrashlogExampleActivity.java sJni.setLogPath(path); // log path 결정 sJni.setAppVersion(APP_VERSION); // 앱 버전 결정 ``` ##Test 앱에서 force crash 버튼을 누르면 {ExternalStorageDirectory}/crashlog/crash.txt 파일이 생성됩니다. ``` cat {ExternalStorageDirectory}/crashlog/crash.txt Time : 2014-07-29 15:11:08 KST Build fingerprint: 'samsung/c1skt/c1skt:4.3/JSS15J/E210SKSUGND1:user/release-keys' pid: 31788, tid: 31788, name: xample.crashlog >>> com.example.crashlog <<< signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00000000 r0 41e25b00 r1 a5b0001d r2 00000001 r3 00000000 r4 57e7ead0 r5 41e247c0 r6 00000000 r7 400a9dd4 r8 bef702a0 r9 400a9dcc sl 41e247d0 fp bef702b4 ip 5c5f8409 sp bef702a0 lr 40b3c4d0 pc 5c5f840c backtrace: 17 #00 pc 0000240c /data/app-lib/com.example.crashlog-1/libcrashlog.so (Java_com_example_crashlog_CrashlogExampleJni_forceCrash+3) #01 pc 0001e4cc /system/lib/libdvm.so (dvmPlatformInvoke+112) #02 pc 0004e99b /system/lib/libdvm.so (dvmCallJNIMethod(unsigned int const*, JValue*, Method const*, Thread*)+398) #03 pc 00050651 /system/lib/libdvm.so (dvmResolveNativeMethod(unsigned int const*, JValue*, Method const*, Thread*)+256) #04 pc 000278e0 /system/lib/libdvm.so #05 pc 0002be80 /system/lib/libdvm.so (dvmInterpret(Thread*, Method const*, JValue*)+184) #06 pc 00060dbb /system/lib/libdvm.so (dvmInvokeMethod(Object*, Method const*, ArrayObject*, ArrayObject*, ClassObject*, bool)+350) #07 pc 00068a7f /system/lib/libdvm.so #08 pc 000278e0 /system/lib/libdvm.so #09 pc 0002be80 /system/lib/libdvm.so (dvmInterpret(Thread*, Method const*, JValue*)+184) #10 pc 00060afd /system/lib/libdvm.so (dvmCallMethodV(Thread*, Method const*, Object*, bool, JValue*, std::__va_list)+292) #11 pc 0004a57b /system/lib/libdvm.so #12 pc 00054e63 /system/lib/libandroid_runtime.so #13 pc 0005638b /system/lib/libandroid_runtime.so (android::AndroidRuntime::start(char const*, char const*)+378) #14 pc 0000105b /system/bin/app_process #15 pc 0000dc4f /system/lib/libc.so (__libc_init+50) #16 pc 00000d7c /system/bin/app_process stack: bef70260 40180000 /system/lib/libc.so (__libc_malloc_dispatch+4294672384) bef70264 00000000 bef70268 5c5f8409 /data/app-lib/com.example.crashlog-1/libcrashlog.so (Java_com_example_crashlog_CrashlogExampleJni_forceCrash) bef7026c 6030c428 bef70270 00000000 bef70274 40145ac1 /system/lib/libc.so (free+12) bef70278 400e6494 bef7027c 40b6e51b /system/lib/libdvm.so bef70280 00000000 bef70284 4006cb1b /system/lib/libbinder.so (android::Parcel::ipcSetDataReference(unsigned char const*, unsigned int, unsigned int const*, unsigned int, void (*)(android::Parcel*, unsigned char const*, unsigned int, unsigned int const*, unsigned int, void*), void*)+26) bef70288 428ebfd0 /dev/ashmem/dalvik-heap (deleted) bef7028c 41e247c0 [heap] bef70290 40bcfc6c /system/lib/libdvm.so bef70294 00000001 bef70298 df0027ad bef7029c 00000000 #00 bef702a0 400a9dc8 ........ ........ #01 bef702a0 400a9dc8 bef702a4 00000001 bef702a8 00000000 bef702ac 428ebfd0 /dev/ashmem/dalvik-heap (deleted) bef702b0 401831f4 (__stack_chk_guard+4294664192) bef702b4 40b6c99f /system/lib/libdvm.so (dvmCallJNIMethod(unsigned int const*, JValue*, Method const*, Thread*)+402) #02 bef702b8 400a9dc8 bef702bc 5f152f84 /data/dalvik-cache/data@app@com.example.crashlog-1.apk@classes.dex bef702c0 5c5f8409 /data/app-lib/com.example.crashlog-1/libcrashlog.so (Java_com_example_crashlog_CrashlogExampleJni_forceCrash) bef702c4 41e247d0 [heap] bef702c8 00000000 bef702cc 40b73f1d /system/lib/libdvm.so (dvmAddTrackedAlloc+24) bef702d0 00000000 bef702d4 00000000 bef702d8 428f7ba8 /dev/ashmem/dalvik-heap (deleted) bef702dc 401831f4 (__stack_chk_guard+4294664192) bef702e0 00000012 bef702e4 40b48704 /system/lib/libdvm.so (dvmMalloc(unsigned int, int)+96) bef702e8 00000008 bef702ec 41e247c0 [heap] bef702f0 428f7b88 /dev/ashmem/dalvik-heap (deleted) bef702f4 40bcfc6c /system/lib/libdvm.so ........ ........ #03 bef703d0 57afe4d0 /dev/ashmem/dalvik-LinearAlloc (deleted) bef703d4 40b3c4d0 /system/lib/libdvm.so (dvmPlatformInvoke+116) bef703d8 400a9bac bef703dc 00000001 bef703e0 00000000 bef703e4 57afe4d0 /dev/ashmem/dalvik-LinearAlloc (deleted) bef703e8 41e247c0 [heap] bef703ec 40b6c9a7 /system/lib/libdvm.so (dvmCallJNIMethod(unsigned int const*, JValue*, Method const*, Thread*)+410) bef703f0 400a9bac bef703f4 595e3e26 /system/framework/framework.odex bef703f8 402a5ae7 /system/lib/libandroid_runtime.so bef703fc 41e247d0 [heap] bef70400 00000000 bef70404 401831f4 (__stack_chk_guard+4294664192) bef70408 a5a0001d bef7040c 00000000 ........ ........ #04 bef70508 2f617661 bef7050c fffffe58 bef70510 40b4c79c /system/lib/libdvm.so (dvmMterpStd(Thread*)) bef70514 00000000 bef70518 bef705d0 [stack] bef7051c 41e247c0 [heap] bef70520 bef7053c [stack] bef70524 57bb76b8 /dev/ashmem/dalvik-LinearAlloc (deleted) bef70528 428b0d24 /dev/ashmem/dalvik-heap (deleted) bef7052c 40b49e84 /system/lib/libdvm.so (dvmInterpret(Thread*, Method const*, JValue*)+188) ``` [1]: https://raw.githubusercontent.com/seodong/crashlog/master/screens.png
