I have another good mod to suggest which I find very useful when looking for apps in /data/apps and all I know is the app name(not helping in there). Same goes for app data. I remember having this on AOKP ROM I was using with my old phone and really missing it.

Anyway...

In SecSettings.apk:

Create new layout res/layout/manage_applications_item2.xml, basically a copy of manage_applications_item.xml with added TextView for app package name and little tweaking other elements. Adjust views as you like...:

<?xml version="1.0" encoding="utf-8"?>
<GridLayout android:paddingTop="8.0dip" android:paddingBottom="8.0dip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:minHeight="?android:listPreferredItemHeight" android:columnCount="4" android:paddingStart="?android:listPreferredItemPaddingStart" android:paddingEnd="?android:listPreferredItemPaddingEnd"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView android:layout_gravity="center_vertical" android:id="@id/app_icon" android:layout_width="@*android:dimen/app_icon_size" android:layout_height="@*android:dimen/app_icon_size" android:scaleType="centerInside" android:contentDescription="@null" android:layout_rowSpan="3" android:layout_marginEnd="8.0dip" />
<TextView android:textAppearance="?android:textAppearanceMedium" android:ellipsize="marquee" android:layout_gravity="fill_horizontal" android:id="@id/app_name" android:layout_width="0.0dip" android:layout_marginTop="2.0dip" android:singleLine="true" android:layout_columnSpan="2" android:textAlignment="viewStart" />
<TextView android:id="@id/app_package_name" android:textAppearance="?android:textAppearanceSmall" android:layout_gravity="fill_horizontal" android:textAlignment="viewStart" android:textColor="#ff33b5e5" android:singleLine="true" android:layout_width="0.0dip" android:ellipsize="marquee" android:layout_columnSpan="2"/>
<com.sec.android.touchwiz.widget.TwCheckBox android:layout_gravity="center_vertical" android:id="@id/app_on_sdcard" android:focusable="false" android:visibility="gone" android:clickable="false" android:layout_rowSpan="2" android:layout_marginStart="8.0dip" />
<TextView android:textAppearance="?android:textAppearanceSmall" android:layout_gravity="fill_horizontal|top|center" android:id="@id/app_size" android:layout_width="wrap_content" android:textAlignment="viewStart" android:singleLine="true"/>
<TextView android:textAppearance="?android:textAppearanceSmall" android:layout_gravity="top" android:id="@id/app_disabled" android:layout_marginStart="8.0dip" />
</GridLayout>

Edit res\layout\installed_app_details.xml by replacing original layout manage_applications_item with manage_applications_item2:

...
<include android:id="@id/app_snippet" layout="@layout/manage_applications_item[COLOR="SeaGreen"]2[/COLOR]" />
...

Add new item in res\values\ids.xml:

...
<item type="id" name="app_package_name">false</item>
...

Add new id's in res\values\public.xml:

...
<public type="layout" name="manage_applications_item2" id="0xYYYYYYYY" />
<public type="id" name="app_package_name" id="0xXXXXXXXX" />
...

Add new code in smali\com\android\settings\applications\InstalledAppDetails.smali and adjust line numbers after:

...
.line 912
iget-object v2, p0, Lcom/android/settings/applications/InstalledAppDetails;->mAppEntry:Lcom/android/settings/applications/ApplicationsState$AppEntry;

iget-object v2, v2, Lcom/android/settings/applications/ApplicationsState$AppEntry;->icon:Landroid/graphics/drawable/Drawable;

invoke-virtual {v0, v2}, Landroid/widget/ImageView;->setImageDrawable(Landroid/graphics/drawable/Drawable;)V

[COLOR="SeaGreen"] .line 913
const v0, 0xXXXXXXXX [COLOR="Red"]#put your id_ from public.xml[/COLOR]

invoke-virtual {v1, v0}, Landroid/view/View;->findViewById(I)Landroid/view/View;

move-result-object v0

check-cast v0, Landroid/widget/TextView;

.line 914
iget-object v2, p0, Lcom/android/settings/applications/InstalledAppDetails;->mAppEntry:Lcom/android/settings/applications/ApplicationsState$AppEntry;

iget-object v2, v2, Lcom/android/settings/applications/ApplicationsState$AppEntry;->info:Landroid/content/pm/ApplicationInfo;

iget-object v2, v2, Landroid/content/pm/ApplicationInfo;->packageName:Ljava/lang/String;

invoke-virtual {v0, v2}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V[/COLOR]

[COLOR="DeepSkyBlue"].line 915[/COLOR]
const v0, 0x7f0b0050

invoke-virtual {v1, v0}, Landroid/view/View;->findViewById(I)Landroid/view/View;

move-result-object v0

check-cast v0, Landroid/widget/TextView;

[COLOR="DeepSkyBlue"].line 916[/COLOR]
iget-object v2, p0, Lcom/android/settings/applications/InstalledAppDetails;->mAppEntry:Lcom/android/settings/applications/ApplicationsState$AppEntry;

iget-object v2, v2, Lcom/android/settings/applications/ApplicationsState$AppEntry;->label:Ljava/lang/String;

invoke-virtual {v0, v2}, Landroid/widget/TextView;->setText(Ljava/lang/CharSequence;)V
....

And you get package name in settings -> apps manager -> app details.:good:
