sdk developed by the buddy supports horizontal and vertical screen switching), because in AndroidManifest. the android: configChanges attribute is not configured in xml. In this case, the Activity re-calls the onCreate method, that is, the entire lifecycle is re-called. At this time, the Dialog has no dismiss, this results in form leakage. The solution becomes so simple, in AndroidManifest. configure the a

However, you must note that this action requires permissions.android.permission.CALL_PHONEIf the permission is not added to the AndroidManifest. xml file of the applicationstartActivity(intent)In this Code, an exception is thrown and the application crashes and exits. The following is the sample code: // Intent. ACTION_DIAL: only dial-up, no call // Intent intent = new Intent (Intent. ACTION_DIAL); // Intent. A

Analysis of Four Android Components1. Features of the four major components * an activity is usually a separate screen (window). The Activity communicates with each other through Intent. In android applications, each Activity must be in AndroidManifest. declared in the xml configuration file, otherwise the system will not recognize or execute the Activity. * The startup and binding services are used to complete user-specified operations in the backgro

Errors and solutions for all Android Developers We know that as developers, we need to have a wealth of professional knowledge and rigorous thinking. We will encounter one or more errors during development. By learning about Android online at the Ding Emy, I listed nine common Android development errors and solutions: 1. If the R file of your project is missing, you can try to save the version number. The R file is usually caused by layout text errors. 2. The layout file cannot contain uppercase

ArticleDirectory 1. Use apktool to decompile our target file 2. Obtain the package name and activity name of any program. 3. The next step is to trigger behavior through monkeyrunner. Monkeyrunner can be used for automated testing. It can also be used for behavior triggering during dynamic analysis in Android. However, it is quite limited to use monkeyrunner for behavior triggering. For example, it is difficult for me to call the simulator or send text messages. If you

process when the user changes the screen direction. We can rewrite this method to restore some temporary data. Onrestoreinstancestate is called after onstart. After the above three relatively unfamiliar methods are introduced, let's take a look at this activity to see what the lifecycle is like: 1. Start activity: After the system calls oncreate and onstart, onresume is called. Since then, the activity enters the execution status. 2. Jump to another activity, or press the Home Key to return to

Switching between landscape and Landscape) Blog type: Android_app Abstract 1: During Game Development, some games can only be played on a horizontal screen. Therefore, when mobile phones are erected and placed, the game screen must be kept on a horizontal screen. At the beginning of game development, it is best to determine whether to use a horizontal screen or a vertical screen. if you can tolerate screen conversion, you not only need to make two interface la S, but also the horizontal an

knowledge, techniques, and time. 1. APK file IntroductionAPK is the abbreviation of Android package, that is, the android application package file or the android installation package. Every application to be installed on the Android platform must be compiled and packaged into a separate file with the extension. APK. The APK file is a file package compiled by professional software ECLIPSE, which contains the binary code, resources, and configuration files of the application. You can install the

I. Introduction to the principle of text message listening the purpose of text message listening is to eavesdrop on text messages sent by someone. For example, we have installed this app on a's mobile phone and want to check the text message sent by B to; How can we get short messages? If a message is sent to a third party via SMS, the message is displayed. Therefore, the message can be sent to the Web server over the network. The messaging application in the Android mobile phone is just a commo

remote Bluetooth device based on the Bluetooth address. Getbondeddevices () Get all pairs of Bluetooth adapter objects Disable () Disable BluetoothEnable () enables Bluetooth. This method does not display a prompt; In more cases, we need to ask whether the user can enable the service. The two lines of code also enable Bluetooth, but the user will be prompted: // Create an intent object used to start an activity and prompt the user to create a bluetooth deviceIntent intent = new intent (effectha

Requirement Description: in some cases, our program needs to run automatically after it is started. When the system is about to close, some records can be written to the specified file. I. Boot broadcast listening: After the Android system is started, the launch completion broadcast (Android. Intent. Action. boot_completed) will be sent. All receivers registered with the broadcast that receive the launch completion broadcast (broadcastreceiver) will receive the broadcast. 1. Add the permission g

processing permissions can be directly displayed in Android, for example, in androidmanifest. in xml, the read or write permissions are declared. In the Provider node, the android: writePermission or android: readPermission attributes are declared. Of course, other programs can also declare these permissions. In this case, we can use android: the authorities attribute limits access to a class, such as android: authorities = "cn.com. android. cwj ". E

. A libs, demo, development manual, and an update document are displayed. 3. Create an application on the official website Simply enter the application name and platform, and click Next To Get The APP_ID. You do not need to download the SDK. 4. Create a Cocos2d-x Project This does not need to be explained. The cocos new command in the console is created. 5. Copy the AppOffer_2.1.1.jar in libs under the Jar package WapsOffer_ForCocos2dx_1.1 to the Android directory of the Cocos project cre

integration detection feature is turned on by default in the SDK after the v2.4 version, and after you call any of the update interfaces, we will automatically check that the 2 and 32 steps in the integration process have been completed correctly. If there are no prompts to complete correctly, you will be prompted with the following toast. You can disable this feature by calling Umengupdateagent.setupdatecheckconfig (false). Toast has the following meanings: "Please copy all resources (res/) fr

Bluetooth data transfer problemFor Bluetooth, Google has encapsulated a lot of API so it is not very difficult to use, but the real development of Bluetooth development is not the most headache of how to invoke the API, but the interaction of data, such as long connection, data continuation, hardware acceptance rate and other issues.There are several ways to turn on Bluetooth?First of all, we first understand the following several commonly used open methods. The first method is relative

In AndroidProgramThe interface is always in one direction and does not change with the phone direction: you only need to configure it in androidmanifest. xml. Add the Android: screenorientation = "Landscape" attribute to the androidmanifest. XML activity (activity that requires no redirection) configuration (landscape is horizontal and portrait is vertical ). For example: In addition, the activity

Today, I read the textbook and sorted out the broadcast content in Android. What we write is actually a broadcast receiver. First we have to write a class that inherits broadcastreceiver and then rewrite the onreceive method in it. Some of our operations are written in this method. We can implement many functions for broadcasting. For example, we can monitor battery power, spam messages, and blacklist. There are two methods for registering: the first method isCodeRegister. The second is to reg

Add a new activity We have learned that an activity is equivalent to an interface (of course.) This is not strict, but easy to understand). After we create an Android app. is created by default:①, a class that inherits activity (which implements the OnCreate method of the parent class and Setcontentview (R.layout.activity_main));②, a default layout file (under the Res-layout directory).③, a ( android app manifest (androidmanifest) However, the Androi
