There is one additional factor in the example above that only applies in the second-discussed situation (i.e. when a plugin launches an external activity). Not only was the state of the application lost when the user finished taking a photo, but so was the photo that the user took. Normally, that photo would be delivered to your application through the callback that was registered with the camera plugin. However, when the Webview was destroyed that callback was lost forever. Luckily, cordova-android 5.1.0 and above provide a means for getting the result of that plugin call when your application resumes.
When the OS destroys the Cordova activity that was pushed into the background by a plugin, any pending callbacks are lost as well. This means that if you passed a callback to the plugin that launched the new activity (e.g. the camera plugin), that callback will NOT be fired when the application is recreated. However, starting in cordova-android 5.1.0, the resume event's payload will contain any pending plugin results from the plugin request that launched the external activity made prior to the activity being destroyed.
Below is a brief example application that uses the resume and pause events to manage state. It uses the Apache camera plugin as an example of how to retrieve the results of a plugin call from the resume event payload. The portion of the code dealing with the resume's event.pendingResult object requires cordova-android 5.1.0+
This issue is surfacing when already an old version of SDK Manager is in the machine from where the approach of Android build is Changed which requires "android studio". I faced this in Visual Studio that was repeatedly halted with Error Message, "You have not accepted the License for version 25". The solution for this is "Install the Android Studio" and then "go to Environment Variables" and set the ANDROID_HOME to "C:\Users\\AppData\Local\Android\Sdk" (This path can be picked from Android Studio, Menu >> Tools >> SDK Manager. Also use the same in "path" of Environment Variables. This way, the new SDK manager is mapped for pickup by Visual Studio Build for Cordova Application.
You should add cordova-plugin-appcenter-analytics and cordova-plugin-appcenter-crashes most every app that uses App Center; they provide useful information for developers without any additional setup or coding.
Note: On a Mac cordova run ios will open the iOS Simulator. A good option for emulating android devices is with GenyMotion that lets you install and run popular android devices as a Virtual Machine (VM). Once the VM is running, cordova run android will install and run the app.
You can run cordova run android to run the compiled application, or cordova run android --device to run on an Android device. Make sure that the device has the developer mode activated, is connected and recognised by the computer.
After installing the Android SDK, you must also install the packages for whatever API level you wish to target. It is recommended that you install the highest SDK version that your version of cordova-android supports.
Cordova 6.1.1 should be used if using SMP 3.0 SP13 SDK.Cordova 6.3.1 should be used if using SMP 3.0 SP14 SDK (Windows requires cordova platform add email@example.com in SP 14).Cordova 6.5.0 should be used if using SMP 3.0 SP15 SDK (Windows requires cordova platform add firstname.lastname@example.org, Android requires cordova platform add email@example.com, and iOS requires firstname.lastname@example.org)Cordova 7.0.1 should be used if using SMP 3.0 SP16 SDK (Windows requires cordova platform add email@example.com, Android requires cordova platform add firstname.lastname@example.org, and iOS requires email@example.com)Cordova 8.0 should be used if using SMP 3.1 SDK (Windows requires cordova platform add firstname.lastname@example.org, Android requires cordova platform add email@example.com, and iOS requires firstname.lastname@example.org)Cordova 9.0 should be used if using SMP 3.2 SDK. This information is also available in the README.md file in the SDK directory.Note, if you use a proxy server you will need to configure npm as shown below.
Prior to the release of email@example.com, you could use the instance of Gradle that Android Studio installed to build the apps you deploy. With the firstname.lastname@example.org release (and later), you must install Gradle separately from Android Studio. For information about how to do this, see Gradle's documentation. 2b1af7f3a8
