我最终删除了声音活动，并且与之关联的所有通话和应用都有效。
尝试添加tabSpec时，我的应用程序强制关闭。我昨天有一个正在运行的版本，但没有保存它，当我编辑它我的规格没有添加正确。我研究的问题基本相同，但这些答案没有帮助。这是我的代码

"Root Granted", Toast.LENGTH_SHORT);
root.show();
} else {

noRoot.show();
finish();
}
Resources res = getResources(); // used to get res drawings (i.e. display files)
TabHost tabHost = getTabHost(); // used to create TabHost located in main.xml
TabHost.TabSpec spec; //TabHost specifications which are the same in each view
Intent intent; //intent for each tab. *RESEARCH INTENT*
// New Class Added Caused FC. Was working. Spec no longer working again.
//____Display
intent = new Intent().setClass(this, DisplayActivity.class);
spec = tabHost.newTabSpec("display").setIndicator("Display",
