When we start android emulator(or is already running), we need to ensure its ready for testing and is responding.
Command line:
This can be ensured by following commands:
Note: 1st and 3rd commands are important to check. Maximum case 2nd command will be ready.
Programmatically:
Also can be done programmatically,
Command line:
This can be ensured by following commands:
adb shell getprop dev.bootcompleteWe need to wait for the above command till it returns 1
adb shell getprop sys_bootcompleteWe need to wait for the above command till it returns 1
adb shell getprop init.svc.bootanimWe need to wait for the above command till it returns "stopped"
Note: 1st and 3rd commands are important to check. Maximum case 2nd command will be ready.
Programmatically:
Also can be done programmatically,
private static String sdkPath = "/Applications/adt-bundle-mac-x86_64-20140702/sdk/"; private static String adbPath = sdkPath + "platform-tools" + File.separator + "adb";
/**
* Waits for the emulator to be ready
*/
public static void waitForEmulatorToBeReady() {
try {
String[] commandBootComplete = new String[] { adbPath, "shell", "getprop", "dev.bootcomplete" };
Process process = new ProcessBuilder(commandBootComplete).start();
BufferedReader inputStream = new BufferedReader(new InputStreamReader(process.getInputStream()));
// wait till the property returns '1'
while (!inputStream.readLine().equals("1")) {
process.waitFor(1, TimeUnit.SECONDS);
process = new ProcessBuilder(commandBootComplete).start();
inputStream = new BufferedReader(new InputStreamReader(process.getInputStream()));
}
String[] commandBootAnim = new String[] { adbPath, "shell", "getprop", "init.svc.bootanim" };
process = new ProcessBuilder(commandBootAnim).start();
inputStream = new BufferedReader(new InputStreamReader(process.getInputStream()));
// wait till the property returns 'stopped'
while (!inputStream.readLine().equals("stopped")) {
process.waitFor(1, TimeUnit.SECONDS);
process = new ProcessBuilder(commandBootAnim).start();
inputStream = new BufferedReader(new InputStreamReader(process.getInputStream()));
}
System.out.println("Emulator is ready to use!");
} catch (Exception e) {
e.printStackTrace();
}
}
You can ensure if an emulator or device is already running before using the above method or commands by the post Checking if android emulator or device is running
