如何獲取Android中已安裝的應用程序列表？

Question

這是源代碼...

public class GetAppList extends Activity {    
    @Override
    public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    try {
        List<PackageInfo> appListInfo = this.getPackageManager()
        .getInstalledPackages(0);
        JSONArray ja = new JSONArray();
        for (PackageInfo p : appListInfo) {
            if (p.applicationInfo.uid > 10000) {
                JSONObject jo = new JSONObject();
                jo.put("label", p.applicationInfo.name);
                jo.put("packageName", p.applicationInfo.packageName);
                ja.put(jo);
            }


        }
        System.out.println(ja);
    } catch (Exception e) {
        // TODO: handle exception
    }

    }
}

這是結果〜

[{“ packageName”：“ com.android.soundrecorder”}，{“ packageName”：“ com.android.alarmclock”}，{“ packageName”：“ com.android.sdksetup”}，{“ packageName”：“ com .android.launcher“}，{” packageName“：” com.google.android.providers.enhancedgooglesearch“}，{” packageName“：” com.gameloft.android.ANMP.GloftAsphalt5.asphalt5“}，{” packageName“： “ com.android.contacts”}，{“ packageName”：“ com.zhang7nan.android”}，{“ packageName”：“ com.android.inputmethod.latin”}，{“ packageName”：“ irdc.ex03_19”} ，{“ packageName”：“ com.android.calculator2”}，{“ packageName”：“ com.zhang7nan.getAppList”}，{“ packageName”：“ com.android.htmlviewer”}，{“ packageName”：“ com .androidbook.layout“}，{” packageName“：” irdc.EX05_04“}，{” packageName“：” com.android.browser“}，{” packageName“：” com.android.customlocale“}，{” packageName “：” com.android.music“}，{” packageName“：” com.android.netspeed“}，{” packageName“：” com.android.providers.userdictionary“}，{” packageName“：” com.android .inputmethod.pinyin“}，{” packageName“：” android.tts“}，{” packageName“：” com.android.providers.media“}，{” package 名稱“：” com.android.globalsearch“}，{” packageName“：” com.wd.AndroidDaemon“}，{” packageName“：” com.android.fallback“}，{” packageName“：” com.gameloft。 android.GAND.GloftBia2.bia2“}，{” packageName“：” com.android.gesture.builder“}，{” packageName“：” org.lee.android“}，{” packageName“：” android.tether“ }，{“ packageName”：“ com.android.providers.contacts”}，{“ packageName”：“ com.android.providers.applications”}，{“ packageName”：“ com.android.providers.drm”}， {“ packageName”：“ com.android.term”}，{“ packageName”：“ com.android.development”}，{“ packageName”：“ com.android.packageinstaller”}，{“ packageName”：“ com。 svox.pico“}，{” packageName“：” com.android.camera“}，{” packageName“：” jp.co.omronsoft.openwnn“}，{” packageName“：” com.android.email“}， {“ packageName”：“ com.wandoujia.wandouapp”}，{“ packageName”：“ com.android.spare_parts”}，{“ packageName”：“ com.android.providers.downloads”}“]

Answer 1

以下是說明您要執行的操作的代碼段：

    public InstalledPackage(PackageManager pm, ApplicationInfo ai, Drawable defaultIcon) {
        name = ai.packageName;
        icon = defaultIcon;
        pkg = ai.packageName;
        if (ai.labelRes != 0) {
            name = (String) pm.getText(ai.packageName, ai.labelRes, ai);
        }
        if (ai.icon != 0) {
            icon = pm.getDrawable(ai.packageName, ai.icon, ai);
        }
    }

請記住，許多包裝都沒有標簽。

解：

    JSONArray ja = new JSONArray();
    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost request = new HttpPost(sendDataUrl.toString());
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        PackageManager pm = context.getPackageManager();
        List<PackageInfo> appListInfo = pm.getInstalledPackages(0);
        for (PackageInfo p : appListInfo) {
            if (p.applicationInfo.uid > 10000) {
                JSONObject jo = new JSONObject();
                jo.put("label", p.applicationInfo.loadLabel(pm).toString());
                jo.put("packageName", p.applicationInfo.packageName);
                ja.put(jo);
            }

        }
