### 2. Installing Android Studio and Android toolchain
You may download and install the latest version of Android Studio [here](https://developer.android.com/studio#downloads). After installing, start Android Studio, and go through the "Setup Wizard." This installs the latest Android SDK, Android SDK Command-line Tools, and Android SDK Build-Tools, which are required by CakeWallet. **Be sure you are installing SDK version 28 or later when stepping through the wizard**
Need to install flutter with version `3.19.x`. For this please check section [Install Flutter manually](https://docs.flutter.dev/get-started/install/linux#install-flutter-manually).
Verify that the Android toolchain, Flutter, and Android Studio have been correctly installed on your system with the following command:
`$ flutter doctor`
The output of this command will appear like this, indicating successful installations. If there are problems with your installation, they **must** be corrected before proceeding.
```
Doctor summary (to see all details, run flutter doctor -v):
You will be prompted to create two passwords. First you will be prompted for the "store password", followed by a "key password" towards the end of the creation process. **TAKE NOTE OF THESE PASSWORDS!** You will need them in later steps.
### 6. Acquiring the CakeWallet Source Code
Create the directory that will be use to store the CakeWallet source...
```
$ sudo mkdir -p /opt/android
$ sudo chown $USER /opt/android
$ cd /opt/android
```
..and download the source code into that directory.
We need to generate project settings like app name, app icon, package name, etc. For this need to setup environment variables and configure project files.
Please pick what app you want to build: cakewallet or monero.com.
Build the Monero libraries and their dependencies:
`$ ./build_all.sh`
It is now time to change back to the base directory of the CakeWallet source code:
`$ cd ../../`
Install Flutter package dependencies with this command:
`$ flutter pub get`
Your CakeWallet binary will be built with cryptographic salts, which are used for secure encryption of your data. You may generate these secret salts with the following command:
`$ flutter packages pub run tool/generate_new_secrets.dart`
Next, we must generate key properties based on the secure keystore you generated for Android (in step 5). **MODIFY THE FOLLOWING COMMAND** with the "store password" and "key password" you assigned when creating your keystore (in step 5).
**REMINDER:** The *above* command will **not** succeed unless you replaced the `storePassword` and `keyPassword` variables with the correct passwords for your keystore.
