| <application_id> is usually the package name where the activities are defined. |
| (See: http://tools.android.com/tech-docs/new-build-system/applicationid-vs-packagename) |
| |
| <activity_name> is the Java class name for the activity you want to launch. |
| If the package name of the activity is different from the application ID, the activity name must be |
| a fully-qualified name (e.g., com.yourcompany.yourapp.MainActivity). |
| |
| If either <application_id> or <activity_name> is provided, the other must be provided as well. |
| |
| |
| If no arguments are specified, madb automatically determines which app to launch, based on the build |
| scripts found in the current working directory. |
| |
| 1) If the working directory contains a Flutter project (i.e., has "flutter.yaml"), this command will |
| run "flutter start --android-device-id=<device serial>" for all the specified devices. |
| |
| 2) If the working directory contains a Gradle Android project (i.e., has "build.gradle"), this |
| command will run a small Gradle script to extract the application ID and the main activity name. |
| In this case, the extracted IDs are cached, so that "madb start" can be repeated without even |
| running the Gradle script again. The IDs can be re-extracted by clearing the cache by providing |
| "-clear-cache" flag. |
