35 ideas for making a simple app in Android
If you have an idea to make a simple app in Android, you’ve probably already thought of a few. You might even be getting 100 ideas a day and don’t know where to begin. Keeping track of your ideas is tricky, and you may even need to prioritize them. Luckily, many great thinkers kept notebooks. Leonardo Da Vinci, for example, kept several notebooks that contain artwork, designs for futuristic machinery, mathematical equations, and thoughts.
Using the gallery
A gallery application displays images on the phone. These applications can be used as portfolios, visual guides, and so on. The first step in creating a gallery app is to obtain the thumbnails for the images you’re displaying. This can be achieved by using a dynamic directory list, which will display new images every time the app is opened. You can also use images from the web. Here are some examples of apps that use the gallery.
Using the notes app

It is a good way to measure time and will mostly benefit athletes and people involved in sports. Using the stopwatch application is easy, and the result will be the same as using the timer application. The app can also be changed in size and moved to your lock screen. You can customize its appearance and style by adding more circles.
You can add various settings for this stopwatch. You can store data for individual measurement circles in the stopwatch’s drop-down menu. Moreover, you can create graphs of these data and export them in an external file. You can even make it appear on your home screen, so that users can easily access its settings. And finally, if you’re working out and want to track your progress in speed cube training, you can use the stopwatch to manage your workout schedule.
Adding a stopwatch to your Android app is easy and doesn’t require much knowledge of Java. Using the stopwatch in Android can be a fun activity, and it is a great way to measure time. While creating a stopwatch app, you may even want to use it as a counting counter. Simply set an initial value and decrement until the count reaches zero. Then, use the stopwatch to generate notifications for the foreground service.
The stopwatch app is a useful tool that many users use on their phones. It is so widely used that many companies have created in-built stopwatch apps for android devices. Creating a stopwatch application in Android will introduce you to the date and time management features in Android Studio. It also offers useful functions for text view. This application is perfect for sports professionals and anyone else who needs to keep track of time.
The running activity is the presentation layer of an Android application. This activity is what the user sees and interacts with, so it is the focus of the application. Android has only one running activity at any given time, so it gets priority in resources and memory. The zippy running activity is a crucial part of the performance of any Android app. However, if you’d prefer to not use an activity, it’s possible.
Activity is the presentation layer of an Android app
An Android application consists of three components: activities, views, and objects. Each of these components plays a specific role in the running of the application. Depending on the design of an application, activities may be single or multiple. They all have a lifecycle, and help the user interact with the application. To understand how activities work, let’s first look at what they are. The Activity class is the building block for an Android application.
An Activity class has two main parts: the UI and the layout. The UI is defined in the Android layout file, and the layout is defined in the code. When an application is launched, Studio creates an initial activity class, called MainActivity. Each activity can contain one or several sub-activities. Activity lifecycle is implemented by calling callback methods. Rotating the device simulates the lifecycle of an activity.
A presentation is a special type of dialog. Its main purpose is to present content on a secondary display. It is associated with the target display at creation time and configures its context according to the display metrics. This is different from the context associated with the containing activity. The presentation uses its own set of display metrics to make sure it displays the correct content on the screen. It’s responsible for creating an object and calling its method when the user performs a specific action.
In order to make use of an Android application’s presentation layer, it is essential to understand how an Activity works. In Android, the Activity is the entry point for the user to interact with an app. It provides the window on which the app can draw UI. The window in an activity class typically fills the entire screen, but may be smaller or float on top of other windows. One Activity class implements a single screen.
It is used to interact with the user
The basic building block of an Android application is an Activity. This UI-based component handles interactions with the user. While Activities can be grouped into a single UI component, an Activity may also contain multiple sub-activities. For instance, an email application might have several activities, each representing a single screen. While Activities are the main focus of an Android app, Services are used for longer-running operations in the background.
Activities are a fundamental part of an Android application, separating the requirements into conceptual units and making it easier for developers to work on them individually. Activities are the most visible part of an application and can be either interactive or passive. Activities may contain a single or multiple widgets, buttons, or images, depending on the nature of the interaction. An activity is responsible for tracking the current display and previously visited activities.
Another important aspect of an Android application is the Activity class. Every app must contain an activity. An activity is the entry point for the application to interact with the user. Each activity contains a layout containing the user interface. The onKeyDown method is called when the user presses a key. A similar action is performed when the user releases a key. Using the Activity Manager, developers can test individual screens and individual items and see how the app responds to different scenarios.
Activities are called during the runtime life cycle of an application. Unlike other environments, Android is a managed container environment. As a result, an activity’s lifecycle is very similar to that of Java applets or servlets. An activity is a reusable component of an application that allows it to transition between different states. However, it must handle the death of a process in a specific order.
It is restricted from being installed on devices without an activity
You may wonder how you can prevent malicious apps from installing on your phone or tablet. Android’s restrictions place a number of different restrictions on the permissions that apps may ask for, such as the ability to see who’s calling and to make phone calls. While some apps require this permission, others do not, so these restrictions prevent users from allowing malicious apps to use their phone or tablet to spy on them.
In October 2015, Google released a new system that allows users to choose which permissions they allow an app to have. These permissions are requested after the app is installed and should be carefully considered before installing any new apps. Without location, Google Maps cannot give you directions to your destination and Zoom cannot connect to video meetings. Fortunately, Android has been improving its security system since then. However, some apps still require access to location and microphone information, which may pose a security risk to users.
It can be made without an activity
An Android app cannot exist without an activity. Activities are a key part of the application model and are what users see when they launch the app. The Android operating system initiates code within an Activity instance by calling callback methods corresponding to certain stages in the Activity’s lifecycle. The Android documentation provides lightweight guidance on how to work with activities. A good example is an email application, which can have many different activities.
In general, an Android app is made up of several activities, each describing a different part of the application. In a mapping application, for example, an activity may contain a list of places to map, a map graphic, and default windows for drawing visual elements. In Android, activities use a set of objects known as «views» that are organized hierarchically. These objects provide the user interface with a variety of options, such as a label and an icon.
Ways to make an Android app without an activity
There are several ways to make an Android app without an activity. The first and most obvious way is to block the main thread of the application. While this will prevent the application from responding to user actions, it can also cause the app to stop responding to feedback. Here are some of those ways. Changing the main thread can cause ANR. You can also change the default activity if you need to. The best way to do this is to modify your app’s XML code.
The second way to create an Android app without an activity is to create a new Java/Kotlin file. You will need to learn how to use Kotlin and Java as well as different folders and views. This will save you a lot of time and frustration. Moreover, you will gain a better understanding of how Android’s system works. It is important to understand the basics of both Java and Kotlin before trying to build an app without an activity.
