按键屏蔽

屏蔽返回键

public boolean onKeyDown(int keyCode, KeyEvent event) {

    switch (keyCode) {
        case KeyEvent.KEYCODE_BACK:
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

屏蔽home键

public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}

屏蔽其他实体按键

switch (keyCode) {
    case KeyEvent.KEYCODE_HOME:
        return true;
    case KeyEvent.KEYCODE_BACK:
        return true;
    case KeyEvent.KEYCODE_CALL:
        return true;
    case KeyEvent.KEYCODE_SYM:
        return true;
    case KeyEvent.KEYCODE_VOLUME_DOWN:
        return true;
    case KeyEvent.KEYCODE_VOLUME_UP:
        return true;
    case KeyEvent.KEYCODE_STAR:
        return true;
}

屏蔽home键后全屏消失说明你是在代码中设置全屏的，转到AndroidManifest.xml设置全屏就行

（可解决不能同时屏蔽home/back键）

为CoreData添加版本管理

/**
 Returns the persistent store coordinator for the application.
 If the coordinator doesn't already exist, it is created and the application's store added to it.
 */
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator {
    if (persistentStoreCoordinator_ != nil) {
        return persistentStoreCoordinator_;
    }
    
    NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"golf.sqlite"];
    
    NSError *error = nil;
    persistentStoreCoordinator_ = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];
    
    
    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                             [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
                             [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; 
    
    if (![persistentStoreCoordinator_ addPersistentStoreWithType:NSSQLiteStoreType
                                                   configuration:nil 
                                                             URL:storeURL 
                                                         options:options 
                                                           error:&error]) {
        
        NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
        abort();
    }    
    
    return persistentStoreCoordinator_;
}

google map 开发
1.获取MD5码，在eclipse：Window-preference-android-build中找到：Debug key store的位置，然后再终端（java环境变量已经配置）输入：
keytool -list -alias androiddebugkey -keystore "/home/smile/.android/debug.keystore" -storepass android -keypass android
然后生成MD5码了：
Certificate fingerprint (MD5): B4:ED:DA:3E:C1:59:7E:A3:0F:D7:EC:A2:CD:A0:0C:07

2.访问http://code.google.com/android/add-ons/google-apis/maps-api-signup.html，输入MD5码，生成key

3. xml文件中：<com.google.android.maps.MapView
                 android:layout_width="fill_parent"
                 android:layout_height="fill_parent"
                 android:apiKey="0JBFjNUzYoEqDk1aEJaD139r-4zkEtC27X5GHNQ"
                 />
