内部的service报错(适用broadcast)

java.lang.InstantiationException: class has no zero argument constructor

我为了共享定位信息把locationservice放到activity

首先是遇到了找不到service.class的问题Intent里面，mainifest文件声明service也报错，后来发现是需要声明为public。所以我就想非显式调用

5.0以上不允许非显式调用的问题

参考 http://blog.youkuaiyun.com/shenzhonglaoxu/article/details/42675287

查了网上解决方案

public static Intent createExplicitFromImplicitIntent ( Context context , Intent implicitIntent ) {

// Retrieve all services that can match the given intent

PackageManager pm = context . getPackageManager ();

List < ResolveInfo > resolveInfo = pm . queryIntentServices ( implicitIntent , 0 );

// Make sure only one match was found

if ( resolveInfo == null || resolveInfo . size () != 1 ) {

return null ;

}

// Get component info and create ComponentName

ResolveInfo serviceInfo = resolveInfo . get ( 0 );

String packageName = serviceInfo . serviceInfo . packageName ;

String className = serviceInfo . serviceInfo . name ;

ComponentName component = new ComponentName ( packageName , className );

// Create a new intent. Use the old one for extras and such reuse

Intent explicitIntent = new Intent ( implicitIntent );

// Set the component to be explicit

explicitIntent . setComponent ( component );

return explicitIntent ;

}

转化

Intent serviceIt = new Intent ( createExplicitFromImplicitIntent ( this , tmpIntent ));

startService ( serviceIt );

最后解决了非显式问题后启动应用又报错：

java.lang.InstantiationException: class has no zero argument constructor

我看字面意思是没有无参构造函数

所以我自己添加了无参构造函数

结果还是报相同错

后来上网查资料发现 http://stackoverflow.com/questions/29947038/java-lang-instantiationexception-class-has-no-zero-argument-constructor

inner Broadcast receiver must be static ( to be registered through Manifest)

所以我把这个locationService声明为static就好了

前后调试找资料花费了挺多时间，记录一下
