2. Execute the following command in your project's root directory:

SMCK will generate a static analysis report, with the report file located in the build/reports/smck directory.

Sample Code:
Here is a simple example showcasing the usage of SMCK for static code analysis within your Android project:

class MyActivity : AppCompatActivity() {

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // Null pointer exception
    val str: String? = null
    println(str)

    // Memory leak
    val view = findViewById<View>(R.id.button)
    view.setOnClickListener(object : View.OnClickListener {
      override fun onClick(v: View?) {
        // Do nothing
      }
    })

    // Security vulnerability
    val password = "123456"
    val textView = findViewById<TextView>(R.id.password)
    textView.text = password
  }
}

Execute the following command:

smck analyze

SMCK will generate the following static analysis report:

• [WARNING] NullPointerException
  at MyActivity.onCreate(MyActivity.kt:10)
• [WARNING] MemoryLeak
  at MyActivity.onCreate(MyActivity.kt:15)
• [WARNING] SecurityVulnerability
  at MyActivity.onCreate(MyActivity.kt:20)

Conclusion:
In conclusion, SMCK is a valuable tool for static code analysis in Android application development, offering a wide range of analysis rules, customization capabilities, and detailed analysis reports.
