Question

当我从我自己的应用程序中打开已安装在手机中的应用程序时，我遇到了这个问题。

权限拒绝：启动Intent {act = android.intent.action.MAIN 猫= [android.intent.category.LAUNCHER] 来自的cmp = com.qq.reader / .widget.picbrowser.PictureActivity} ProcessRecord {3823559b 16851：com.pax.market.android.app/u0a322} （pid = 16851，uid = 10322）未从uid导出 10324

  public static void openApp(Activity activity,String packageName) {
    PackageInfo pi;
    try {
        pi = activity.getPackageManager().getPackageInfo(packageName, 0);
        Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
        resolveIntent.setPackage(pi.packageName);
        PackageManager pManager = activity.getPackageManager();
        List apps = pManager.queryIntentActivities(
                resolveIntent, 0);

        ResolveInfo ri = (ResolveInfo) apps.iterator().next();
        if (ri != null) {
            packageName = ri.activityInfo.packageName;
            String className = ri.activityInfo.name;
            Intent intent = new Intent(Intent.ACTION_MAIN);
            intent.addCategory(Intent.CATEGORY_LAUNCHER);
            ComponentName cn = new ComponentName(packageName, className);
            intent.setComponent(cn);
            activity.startActivity(intent);
        }
    } catch (NameNotFoundException e) {
        Log.e(TAG, "Package Name not found: " + e.getMessage() + ", App is not installed.");
    } catch (SecurityException e){
        SnackBar.newBuilder().activity(activity).
                text(activity.getString(R.string.permission_denied_to_open))
                .build().show();
    }
}

列出apps = pManager.queryIntentActivities（resolveIntent，0）; 将会找到多个活动。

例如：appName：QQReader，packagename：com.qq.reader。

你会发现两个活动：

com.qq.reader.widget.picbrowser.PictureActivity

com.qq.reader.activity.SplashActivity

无法启动PictureActivity，因为它的导出= false，可以启动SplashActivity

代码修改如下：

public static void  openApp(Activity activity,String packageName) {
PackageInfo pi;
try {
    pi = activity.getPackageManager().getPackageInfo(packageName, 0);
    Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
    resolveIntent.setPackage(pi.packageName);
    PackageManager pManager = activity.getPackageManager();
    List<ResolveInfo> apps = pManager.queryIntentActivities(
            resolveIntent, 0);
    for(ResolveInfo app: apps){

        Log.d(TAG,String.format("%s %s",app.activityInfo.packageName,app.activityInfo.name));
        packageName = app.activityInfo.packageName;
        String className = app.activityInfo.name;
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        ComponentName cn = new ComponentName(packageName, className);
        intent.setComponent(cn);
        try {
            activity.startActivity(intent);
        }catch(SecurityException e){
            e.printStackTrace();
        }
    }
  /*  ResolveInfo ri = (ResolveInfo) apps.iterator().next();
    if (ri != null) {
        packageName = ri.activityInfo.packageName;
        String className = ri.activityInfo.name;
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        ComponentName cn = new ComponentName(packageName, className);
        intent.setComponent(cn);
        activity.startActivity(intent);
    }*/
} catch (PackageManager.NameNotFoundException e) {
    Log.e(TAG, "Package Name not found: " + e.getMessage() + ", App is not installed.");
} catch (SecurityException e){
    SnackBar.newBuilder().activity(activity).
            text(activity.getString(R.string.permission_denied_to_open))
            .build().show();
}

}

权限拒绝：启动意图未从uid
