Add compiler flags to the standard android build.xml

I want to add -Xlint:deprecated to the java compiler while building android app. I've seen the compilerarg tag inside javac tags, but the generated build.xml for the standard project doesn't have such a tag. Any hint?

the full build script is located YOUR_SDK_FOLDER/platforms/SDKVERSION/templates/android_rules.xml

you modify your build.xml with copy of this file and customize it. Not sure if it'll get where you want - but it's a start

<!-- Execute the Android Setup task that will setup some properties specific to the target,
             and import the rules files.
             To customize the rules, copy/paste them below the task, and disable import by setting
             the import attribute to false:
                <setup import="false" />

             This will ensure that the properties are setup correctly but that your customized
             targets are used.

Configure your build, The Android build system compiles app resources and source code, and The compilers convert your source code into DEX (Dalvik Executable) files, which To find out more, see Add Build Dependencies. There are a few Gradle build configuration files that are a part of the standard Android-specific build options. */ -DCOMPILE_VAR-> Enable flag COMPILE_VAR - It is equivalent to add to the code (#define COMPILE_VAR)-DDO_SOMETHING=1 - Equivalent to add to the code #define DO_SOMETHING = 1-DDISABLE_DEPRECATED_FUNCTIONS=0; Optmization - docs-O0 No optmization, faster compilation time, better for debugging builds.-O2-O3 Higher level of optmization.

There is a java.compilerargs property in the default $SDKDIR/tools/ant/build.xml file that you can override in the in your project, such as:

java.compilerargs=-Xlint:unchecked -Xlint:deprecation

AAPT2, Android Gradle Plugin 3.0.0 and higher enable AAPT2 by default, and you Insert the version name you copied into the following URL and specify XML resource files, such as String and Style, which are located in the res/values/ directory. aapt2 compile path-to-input-files [ options ] -o output-directory /.

Add this to <project>/app/build.gradle (not the global build.gradle):

preBuild {
    doFirst {
        JavaCompile jc = android.applicationVariants.find { == 'debug' }.javaCompile
        jc.options.compilerArgs = ["-Xlint:deprecation"]

Optimize your build speed, Keep your tools up-to-date; Create a build variant for development; Enable The optimization is enabled by default on all projects. Avoid compiling and packaging resources that you aren't testing To prevent Crashlytics from automatically updating its build ID, add the following to your build.gradle file:. You need to use the -J option for passing flags directly to the runtime system. e.g. -J-Xms128m -J-Xmx512m instead of just -Xms128m -Xmx512m in your compilerarg. javac -X is for passing nonstandard options to the compiler. If you run the command javac -X it will display a list of legal options which include the -Xlint that you've used.

Configure build variants, You can add the debug build type to your configuration if you want to add or change certain settings. "full" product flavors, and kept the default "debug" and "release" build types, debug ---- Compile configuration: compile build.gradle name: android. For example, to create a values XML file for your "debug" build type:. Append Compiler Flags. The initial content from the cached CMAKE_CXX_FLAGS variable is a combination of CMAKE_CXX_FLAGS_INIT set by CMake itself during OS/toolchain detection and whatever is set in the CXXFLAGS environment variable. So you can initially call: cmake -E env CXXFLAGS="-Wall" cmake ..

Create and edit run/debug configurations, Typically, the default configuration is sufficient to run or debug an app. However, you Gradle-aware Make, Compile the project and run Gradle. Android Studio stores the shared run/debug configuration in individual XML files under the Installation Options: Install Flags, Type any adb pm install options you want to use. Configure compiler settings. You can configure how you want a compiler to process the code you work on. For example, you can increase the speed of the compilation process, configure the automatic build, process annotations during the compilation time, and so on.

Inject build variables into the manifest, If you need to insert variables into your AndroidManifest.xml file that are By default, the build tools also provide your app's application ID in  It’s really easy but without any knowledge of how android stuff is built with build.xml you don’t know where to start (I did it the other way around, calling java from C++, then compiling java by hand, creating jars and trying to get them into apk, when I learned that build.xml can do all of that for me).
