android捕获错误并处理
利用Thread.UncaughtExceptionHandler 获取异常,并对异常做出处理：
application代码：
public class TestApplication extends Application{
public void onCreate(){
TestException testException = TestException.getInstance();
testException.init(getApplicationContext());
}
}
exception代码：
public class TestException implements UncaughtExceptionHandler {
//获取application 对象；
private Context mContext;
private Thread.UncaughtExceptionHandler defaultExceptionHandler;
//单例声明TestException;
private static TestException testException;
private TestException(){
}
public static TestException getInstance(){
if(testException == null){
testException = new TestException ();
}
return testException ;
}
@Override
public void uncaughtException(Thread thread, Throwable exception) {
// TODO Auto-generated method stub
if(defaultExceptionHandler != null){
Log.e("tag", "exception >>>>>>>"+exception.getLocalizedMessage());
//将异常抛出，则应用会弹出异常对话框.这里先注释掉
// defaultExceptionHandler.uncaughtException(thread, exception);
android.os.Process.killProcess(android.os.Process.myPid());
System.exit(10);
}
}
public void init(Context context) {
mContext = context;
defaultExceptionHandler = Thread.getDefaultUncaughtExceptionHandler();
Thread.setDefaultUncaughtExceptionHandler(this);
}
}
在TestManifest.xml中配置：
<application
android:name="com.test.TestApplication"
android:label="@string/app_name" >
