It doesn't install app on the emulator device.

Please suggest any hints to rectify this error.

My project used to run fine few weeks back. It is giving errors now, without any changes made to code.

Answer 1

I encountered the same problem, and what helped me was setting up the Android development environment correctly. Here’s a step-by-step guide to ensure your environment is configured properly:

Step 1: Set Up Android SDK Path Open your terminal.

Edit your profile file by typing the following command:

vim ~/.profile

If you're using a different shell (e.g., zsh), you might need to edit

~/.zshrc

Add the following lines to set the Android SDK path:

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/platform-tools

Save and exit the editor. In vim, you can do this by pressing Esc, typing :wq, and then pressing Enter.

Step 2: Apply the Changes Source the profile file to apply the changes:

source ~/.profile

If you edited a different file (like ~/.zshrc), source that file instead:

source ~/.zshrc

Step 3: Verify JAVA_HOME Check if JAVA_HOME is defined:

echo $JAVA_HOME

If it returns an empty line or is not set, you need to set it up. Set JAVA_HOME if it's not defined:

export JAVA_HOME=$(/usr/libexec/java_home)

Add this line to your profile file as well to ensure it’s set every time you open a terminal.

Step 4: Additional Debugging If you still face issues, you can try running the build command with more detailed logging:

cd android
./gradlew app:installDebug --stacktrace --info --debug

This will provide more information about what went wrong during the build process.
