我有我的問題。我創建發射活動給它,使用此代碼:動態壁紙「設置壁紙」不工作
Toast toast = Toast.makeText(this, "Choose Photo Live Wallpaper from the list to start the Live Wallpaper.",Toast.LENGTH_LONG); toast.show(); Intent intent = new Intent(); intent.setAction(WallpaperManager.ACTION_LIVE_WALLPAPER_CHOOSER); startActivity(intent); finish();
我宣佈它用這樣的:
<activity android:name=".Launcher" android:label="@string/app_name"
android:screenOrientation="portrait"
android:icon="@drawable/iconn">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<action android:name="android.intent.action.CREATE_SHORTCUT" />
</intent-filter>
</activity>
,它是工作,但是當我在設置壁紙點擊啓動活動重新開始,我不知道爲什麼。 logcat的給我這個錯誤:
chanel '4143dd60 org.me.project.serviceLv (client) ~ Publisher close input chanell or an error ocured event=0x8
感謝所有幫助
這是我的清單文件:

</application>
我添加了所有清單。 Logcat僅顯示此錯誤 – kPawel
放置一個嘗試並捕捉畫布上繪製對象的代碼。例如: - Canvas canvas = null; 嘗試{canvas} = surfaceHolder.lockCanvas(null); synchronized(surfaceHolder) { onDraw(canvas); (canvas!= null) { } surfaceHolder.unlockCanvasAndPost(canvas); } } catch(Exception e){ e.printStackTrace(); } – user2125722
但normaly lv正常工作。問題是當我使用啓動器。 – kPawel
