Android ExampleApp's jni `build.sh` doesn't handle relative pathes for LOG_FILE

**Describe the bug** The `<sdk>/examples/android/ExampleApp/app/src/main/jni/build.sh` script redirects various command output into `$LOG_FILE`, but meanwhile it changes the current working directory multiple times. Thus if we specify a relative path for the `LOG_FILE` variable, `build.sh` will create a number of logfiles in a number of directories. This is most certainly not the expected behaviour. The `<sdk>/examples/android/ExampleApp/README.md` file only says the following: > If you want a more verbose output to inspect the output looking for build errors, change the `LOG_FILE` variable in the build.sh script from `/dev/null` to `/dev/stdout` or to a file like `/tmp/build.log` This doesn't imply (yet) that using an absolute path is mandatory (or else ...). **To Reproduce** Steps to reproduce the behavior: 1. Checkout sdk repo. 2. Change current working directory to `<sdk>/examples/android/ExampleApp/app/src/main/jni`. 3. Run `LOG_FILE=log.txt build.sh all` **Expected behavior** Only one logfile is created. Ideally if the value given to `LOG_FILE` doesn't start with a `/`, the current working directory should be prepended. Currently `LOG_FILE` is initialized like this: ``` if [ -z "${LOG_FILE}" ]; then # If no build log variable is defined, use below value. LOG_FILE=/dev/null # Ensure you use a full path fi ``` Instead it should be something like this: ``` if [ -z "${LOG_FILE}" ]; then # If no build log variable is defined, use below value. LOG_FILE=/dev/null # Ensure you use a full path elsif [ "${LOG_FILE:0:1}" != "/" ]; then LOG_FILE="$(pwd)/$LOG_FILE" fi ``` If this is not a desired solution, the `README.md` should explicitly say that an absolute path should be used, or there'll be a number of logfiles created throughout the tree of the `<sdk>/examples/android/ExampleApp/app/src/main/jni` directory. **Screenshots** I don't think this is necessary, since the bug/issue (and a potential fix) is well described. And it's trivially reproducible. **Environment:** - SDK Version: v9.16.1 - OS: Ubuntu 22.04.5 LTS - Device: Android **Additional context** No additional context.
