    <p>I'm trying to install a prebuilt binary in a custom Android image. For that I have copied it to a new directory in <code>prebuilt/android-arm/</code> with an <code>Android.mk</code> file similar to this one:</p> <pre><code>LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_SRC_FILES := binary_name LOCAL_MODULE := binary_name LOCAL_MODULE_CLASS := EXECUTABLES include $(BUILD_PREBUILT) </code></pre> <p>So if I run <code>make system_image binary_name</code>, the binary file is copied to <code>/bin/</code> in system image. And if I run the emulator I can see the binary file in <code>/system/bin</code>. The permissions are the same as the other executables (<code>-rwxr-xr-x</code>) and, according to <code>file</code>, this is an ARM binary (<code>ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), stripped</code>).</p> <p>But when I run it on the emulator, it says:</p> <pre><code># binary_name binary_name: not found </code></pre> <p>I have straced it and this is what I can see:</p> <pre><code># strace binary_name execve("/system/bin/binary_name", ["binary_name"], [/* 9 vars */]) = -1 ENOENT (No such file or directory) write(2, "strace: exec", 12strace: exec) = 12 write(2, ": ", 2: ) = 2 write(2, "No such file or directory", 25No such file or directory) = 25 write(2, "\n", 1 ) = 1 io_submit(1, -1344063348, {...} &lt;unfinished ... exit status 1&gt; </code></pre> <p>But the file is there, and strace is able to find it.</p> <p>Any idea of what can be happening?</p> <p><strong>UPDATE</strong>: As Kristof says, this is probably a problem of dynamic linking, but I don't have ldd for Android ARM...</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
