The hoser command has failed).Debugging is an essential step of the software development cycle, as it gives the developer a way to check the inner workings of the system and to trace the flow of data and instruction in the program. Steps as mentioned above (for example, gdbclient hoser :5039 if Otherwise you need to determine the path of the crashing binary and follow the To enable a process to be debugged this way, you need to set a property: Would have without this feature (like cylonning), press home (a If you're in the field and just want your device to continue as it System process, most likely your device will be frozen at this point.

If you see the red LED flashing it means a process is in that new Info about other threads will be queried from theīreakpoint is hit or you ask for it by running info thread. Newly created threads so you will not always see notifications about newlyĬreated threads. The gdb remote protocol doesn't have a way for the device to The linker loads libc into your process before hitting main(). You can ignore the error about notįinding the location for the thread creation breakpoint. You should be connected and able to debug as you normally would. You may need to inspire gdb to load some symbols by typing: The :5039 tells gdb to connect to the localhost port 5039, which is bridged to the device by adb. Connect to the device by issuing the gdb command:.Make sure you specify the correct directories gdb may not tell you if you make a mistake. Product-name is the same as above for example, sooner. Set solib-search-path / absolute-source-path/out/target/product/ product-name/symbols/system/libĪbsolute-source-path is the path to your source tree for example, /work/device or /Users/hoser/android/device. Set solib-absolute-prefix / absolute-source-path/out/target/product/ product-name/symbols In gdb, Tell gdb where to find the shared libraries that will get loaded:.Primary android directory, because the one in the primary directory hasīeen stripped of its debugging information. Make sure to use the copy of the executable in the symbols directory, not the Where product-name is the name of the device product that you're building (for example, sooner),Īnd executable is the program to debug (usually app_process for an application).

The :5039 tells gdbserver to listen on port 5039 on the localhost, which adb bridges from the host to the device. For example, to attach theĪlready-running globaltime application, execute the following, making sure that: 1) you do this from the same window used to build the software on the device you are debugging and 2) verify that the symbols in the object files in the build tree match up with what is installed on the device or emulator.Īndroid runs gdbserver on the device and an ARM aware gdb, named arm-eabi-gdb, on the desktop machine. The current version of envsetup.sh has a gdbclient command that handles much of the setup.
