How to input ${sdk.dir} to build.xml | Apache Ant | Ubuntu

Ubuntu RaviTeja   7:47:00 PM

Assuming, $ANDROID_HOME (environmental variable ) refers to android sdk directory, you can inject the ANDROID_HOME  into the sdk.dir property using the following ant command.

$ ant debug -Dsdk.dir=$ANDROID_HOME

ANDROID_HOME must be an absolute path such as /home/username/something/android-sdk

SOLUTION:

1. Upgrade ant that is linked to Buildozer
2. Install using sudo apt-get install ant.
3. If ant is already installed and it is latest, just change the version in specification file of buildozer by following this link.

ANT version change | Buildozer | Ubuntu

ANT version change | Buildozer | Ubuntu

Ubuntu RaviTeja   6:43:00 PM

1. Type which ant in terminal. 
2. Mine resulted with /usr/bin/ant. If apache ant is not installed already, you might get an error.
3. Uncomment #android.ant_path = line in buildozer.spec
4. use android.ant_path = /usr/bin/ant 
5. Now you can control the upgrades of ant and get it updated in buildozer automatically. Otherwise, there will be two instances (can be two different versions) in same machine.

I am trying to build apk using buildozer and below is the error I've encountered:

ant/build.xml :  Unable to resolve project target 'android-19
...

...
Traceback (most recent call last):

Solution:

1. Open Android SDK Manager
2. To launch it we need to cd to /home/username/.buildozer/android/platform/android-sdk-24/tools and execute./android. Do not use sudo ./android as it gives you permissions issue later.
3. Deselect All and select API 19
4. Install and close.

Solution: # Aidl not found, please install it | Ubuntu | Buildozer

Ubuntu RaviTeja   2:43:00 PM

ERROR:

# Check that aidl can be executed

# build-tools folder not found /home/raviteja/.buildozer/android/platform/android-sdk-24/build-tools
# Search for Aidl
# Aidl not found, please install it.

SOLUTION:

1. Above error says build-tools folder is not found. I checked in my /home/raviteja/.buildozer/android/platform/android-sdk-24/ and build tools folder is not available really.
2. Launched Android SDK Manager to install the build tools. To launch it we need to cd to /home/raviteja/.buildozer/android/platform/android-sdk-24/tools and execute ./android. Do not use sudo ./android as it gives you permissions issue later.
3. Make sure you check the following check box in Tools --> Options of Android SDK Manager and close it.
4. 
5. Check the Build tools option and install it (you might need to accept the license)
