審査がある。

15年ごろの3分が 22年では2日に伸びている。

packageName一覧を列挙する

Intent i = getIntent();
pm.getLaunchIntentForPackage("package.name.xxxxx");
@SuppressLint("QueryPermissionsNeeded") List<ResolveInfo> resolve = pm.queryIntentActivities(i, PackageManager.MATCH_ALL);
for (ResolveInfo s : resolve) {
    Log.d("IconResourceID", String.valueOf(s.getIconResource()));
}

アプリが入っていない場合にストアへ飛ばす

try {
    startActivity(intent);
} catch (Exception ignored) {
    // todo: 事前のinstall検証でもいいかもしれない
    try {
        Intent googlePlayIntent = new Intent(Intent.ACTION_VIEW);
        googlePlayIntent.setData(Uri.parse("market://details?id=a.b.c.d"));
        startActivity(googlePlayIntent);
    } catch (Exception ActivityNotFoundException) {
    }
}

指定パッケージを開く

Manifestにqueryを指定する必要が11以降で発生

drawableが22からCompat経由

// 指定している全てのアプリを出そうとするが、入っていない場合もあるため、デフォルトのアイコンを指定
Resources res = getResources();
Drawable icon = ResourcesCompat.getDrawable(res, R.drawable.png, null);
Boolean hasPackage = true;
