  • Android 如何避免运行时奔溃

    奔溃问题

    android运行的时候难免会有一些空指针(NullPointerException)或者下标越界(IndexOutOfBoundsException),用户使用的过程操作某一个按钮的时候,就发生了崩溃.导致app直接闪退,降低用户体验,因此导致用户流失

    1.在项目根目录的build.gradle文件中添加

    allprojects {
        repositories {
            maven { url 'https://dl.bintray.com/xuuhaoo/maven/'}
        }
    }
    

    2. 在项目的build.gradle文件中添加依赖包

    implementation 'com.tonystark.android:defense_crash:2.0.0'
    

    3.在项目的Application中初始化操作

       DefenseCrash.initialize();
            
       DefenseCrash.install(this);
    

     4.在项目的Application中实现 implements IExceptionHandler 接口

        public class MyApp extends Application implements IExceptionHandler {
            @Override
            protected void attachBaseContext(Context base) {
                super.attachBaseContext(base);
                // step1: Initialize the lib.
                DefenseCrash.initialize();
                // setp2: Install the fire wall defense.
                DefenseCrash.install(this);
            }
    
            @Override
            public void onCaughtException(Thread thread, Throwable throwable, boolean isSafeMode) {
                // step3: Print the error when crashed during runtime.
                throwable.printStackTrace();
                // step4: Upload this throwable to your crash collection sdk.
            }
    
            @Override
            public void onMayBeBlackScreen(Throwable throwable) {
                // onLayout(),onMeasure() or onDraw() has breaks down,
                // it causes the drawing to be abnormal and the choreographer to break down.
                // We will notify you on this method,you’d better finish this activity or restart the application.
            }
    
            @Override
            public void onEnterSafeMode() {
                // We enter the safe mode to keep the main looper loop after crashed.You’d better do nothing here,we just notify you.
            }
    
        }
    

     5.大功告成,这样用户在使用app是就不会出现奔溃闪退的现象啦!!!
