Hangup in ActivityThread?_问答_开发者_运维开发者技术经验分享

Any clue why my Android app is hanging on this code block when I try to debug it in Eclipse?

public static final int REMOVE_PROVIDER         = 131;

package com.example.myapp;

import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;

public class TEHWARRiORS extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Resources res = getResources(); // Resource object to get Drawables
        TabHost tabHost = getTabHost();  // The activity TabHost
        TabHost.TabSpec spec;  // Resusable TabSpec for each tab
        Intent intent;  // Reusable Intent for each tab

        // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent().setClass(this, Start.class);

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost.newTabSpec("Start").setIndicator("",
                          res.getDrawable(R.drawable.ic_tab_navbar_admins))
                      .setContent(intent);
        tabHost.addTab(spec);

        // Do the same for the other tabs
        intent = new Intent().setClass(this, Servrar.class);
        spec = tabHost.newTabSpec("Servrar").setIndicator("Servrar",
                          res.getDrawable(R.drawable.ic_tab_navbar_admins))
                      .setContent(intent);
        tabHost.addTab(spec);

        intent = new Intent().setClass(this, Admins.class);
        spec = tabHost.newTabSpec("Admins").setIndicator("Admins",
                          res.getDrawable(R.drawable.ic_tab_navbar_admins))
                      .setContent(intent);
        tabHost.addTab(spec);

        intent = new Intent().setClass(this, Regler.class);
        spec = tabHost.newTabSpec("Regler").setIndicator("Regler",
                       开发者_高级运维   res.getDrawable(R.drawable.ic_tab_navbar_admins))
                      .setContent(intent);
        tabHost.addTab(spec);

        tabHost.setCurrentTab(0);

    }
}

Well, there you go:

05-15 20:46:09.969: ERROR/AndroidRuntime(15352): Caused by: java.lang.RuntimeException: Your content must have a TabHost whose id attribute is 'android.R.id.tabhost'
05-15 20:46:09.969: ERROR/AndroidRuntime(15352):     at android.app.TabActivity.onContentChanged(TabActivity.java:105)

You are using a TabActivity but have replaced its content with something that doesn't have a tab host.

Ok, so the (perhaps not quite useful to you) answer to why it's 'hanging' (by which I assume it's behaving as if a breakpoint was set there) is given here: Why does my Eclipse project have phantom debugger breakpoints?. You can turn it off by unselecting Window > Preferences > Java > Debug : Suspend execution on uncaught exceptions

As to what the exception is that causes this Suspend execution on uncaught exceptions should be visible in the logs, along with the stacktrace - you should edit your question and post that.
