我有两个服务(一个调用另一个服务的 DashClock 扩展服务),第二个服务应该保存一个值,以便我可以使用该值在我的 DashClock 扩展中显示。但是,此值似乎没有传递到扩展服务中。
DashClock 扩展:
@Override
public void onCreate() {
super.onCreate();
be=this;
//numUpdates = getSharedPreferences("PREFERENCE", MODE_PRIVATE).getInt("numUpdates", -1);
Intent i = new Intent(this, UpdateCheckService.class);
i.putExtra(Constants.CHECK_FOR_UPDATE, true);
startService(i);
//numUpdates = getSharedPreferences("PREFERENCE", MODE_PRIVATE).getInt("numUpdates", 0);
registerReceiver(myReceiver, new IntentFilter(Intent.ACTION_TIME_TICK));
}
@Override
protected void onUpdateData(int reason) {
// Get preference value.
final SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
//String name = sp.getString(PREF_NAME, "Eric");
Log.d("hiya","updating");
/*while(getSharedPreferences("PREFERENCE", MODE_PRIVATE).getInt("numUpdates", -1)==-1){
Log.d("wait","waiting here");
}*/
//numUpdates = getSharedPreferences("PREFERENCE", MODE_PRIVATE).getInt("numUpdates", -2);
int numUpdates = sp.getInt("numUpdates", -2);
Log.d("IMPORTANT FROM BrianExtension", "" + numUpdates);
Intent intent = new Intent();
intent.setClassName("com.cyanogenmod.updater", "com.cyanogenmod.updater.UpdatesSettings");
// Publish the extension data update.
if(numUpdates == 0){
shouldShow = false;
} else{
shouldShow = true;
}
publishUpdate(new ExtensionData()
.visible(shouldShow)
.icon(R.drawable.cid)
.status(numUpdates + " updates")
.expandedTitle(numUpdates + " Nightly CM Updates")
.expandedBody("Click here to go to CMUpdater.")
.clickIntent(intent));
}
更新检查服务:
@Override
public void onCreate() {
ucs = this;
registerReceiver(mReceiver, new IntentFilter("updatethis"));
/*prefs = getSharedPreferences("PREFERENCE", Context.MODE_PRIVATE);
prefs.registerOnSharedPreferenceChangeListener(mListener);*/
final SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
Thread thread = new Thread(new Runnable(){
@Override
public void run() {
try {
try {
int ericUpdates = getAvailableUpdates().getUpdateCount(getBaseContext());
Log.d("yes!", ""+ericUpdates);
sp.edit().putInt("numUpdates", ericUpdates).apply();
Log.d("IMPORTANT FROM UpdateCheckService", "" + sp.getInt("numUpdates", -99));
//getSharedPreferences("PREFERENCE", MODE_PRIVATE).edit().putInt("numUpdates", ericUpdates).apply();
//Log.d("IMPORTANT FROM UpdateCheckService", "" + getSharedPreferences("PREFERENCE", MODE_PRIVATE).getInt("numUpdates", -99));
sendBroadcast(new Intent(ucs, BrianUpdaterReceiver.class));
//BrianExtension.be.onUpdateData(4);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
}
});
thread.start();
//stopSelf();
// Get the System Mod string
mSystemMod = TESTING_DOWNLOAD ? "cmtestdevice" : SysUtils.getSystemProperty(Customization.BOARD);
if (mSystemMod == null) {
Log.i(TAG, "Unable to determine System's Mod version. Updater will show all available updates");
}
}
日志显示“numUpdates”首选项中的值在 UpdateCheckService 中是正确的,但在 BrianExtension 中仍为 -2。
