Body
I have a quite simple activity like this : <pre><code>public class SurvivalActivity extends Activity { private static final String KEY_LAYOUT_ID = "SurvivalLayoutId"; int mLayoutId; private static final int[] mSurvivalLayouts = { R.layout.survival1, R.layout.survival2, R.layout.survival3, }; @Override public void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); final Intent i = getIntent(); if (savedInstanceState != null && savedInstanceState.containsKey(KEY_LAYOUT_ID)) { mLayoutId = savedInstanceState.getInt(KEY_LAYOUT_ID, 0); } else if (i != null) { mLayoutId = i.getIntExtra(KEY_LAYOUT_ID, 0); } else { mLayoutId = 0; } // Layout setContentView(mSurvivalLayouts[mLayoutId]); // Title Util.setTitleFont(this, findViewById(R.id.title)); // "Next" button final View nextButton = findViewById(R.id.survival_next); Util.setFont(this, nextButton, "Lobster.ttf"); nextButton.setOnClickListener(new OnClickListener() { @Override public void onClick(final View v) { final Intent next = new Intent(SurvivalActivity.this, SurvivalActivity.class); next.putExtra(KEY_LAYOUT_ID, (mLayoutId + 1) % mSurvivalLayouts.length); startActivity(next); finish(); } }); } @Override protected void onSaveInstanceState(final Bundle outState) { outState.putInt(KEY_LAYOUT_ID, mLayoutId); } } </code></pre> The two Util.* static methods just change the font of the <code>TextView</code>. All 3 layouts are rather simple, let me show you the first : <pre><code><?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <TextView style="@style/Title" android:text="@string/surv1_title" /> <TextView style="@style/Content" android:text="@string/surv1_1" /> <ImageView style="@style/Picture" android:src="@drawable/surv_crafting" /> <TextView style="@style/PicLegend" android:src="@string/surv_crafting_leg" /> <ImageView style="@style/Picture" android:src="@drawable/surv_hache" /> <TextView style="@style/PicLegend" android:src="@string/surv_hache_leg" /> <ImageView style="@style/Picture" android:src="@drawable/surv_pioche" /> <TextView style="@style/PicLegend" android:src="@string/surv_pioche_leg" /> <TextView style="@style/Content" android:text="@string/surv1_2" /> <ImageView style="@style/Picture" android:src="@drawable/surv_charbon" /> <TextView style="@style/PicLegend" android:src="@string/surv_charbon_leg" /> <TextView style="@style/Content" android:text="@string/surv1_3" /> <ImageView style="@style/Picture" android:src="@drawable/surv_torch" /> <TextView style="@style/PicLegend" android:src="@string/surv_torch_leg" /> <TextView style="@style/Content" android:text="@string/surv1_4" /> <ImageView style="@style/Picture" android:src="@drawable/surv_abri" /> <TextView style="@style/PicLegend" android:src="@string/surv_abri_leg" /> <TextView style="@style/Content" android:text="@string/surv1_5" /> <Button style="@style/SurvivalBoxNext" android:text="@string/surv1_next" /> </LinearLayout> </ScrollView> </code></pre> As you can see it's just several <code>TextView</code>s with <code>ImageView</code>s, and a <code>Button</code> that triggers the load of the next activity. I launch the app, it displays the first screen. I scroll down to the button, click, the second screen is displayed (with a hiccup). I scroll down to the button, click, and boom. <pre><code>03-02 16:36:46.488 E/AndroidRuntime(10611): java.lang.RuntimeException: Unable to start activity

Here's my activity code (only variables + <code>onCreate</code> as the rest is identical) <pre><code>private static final int[] mTitles = { R.string.surv1_title, R.string.surv2_title, R.string.surv3_title }; private static final int[][] mTextViews = { { R.string.surv1_1, R.string.surv1_2, R.string.surv1_3, R.string.surv1_4, R.string.surv1_5 }, { R.string.surv2_1, R.string.surv2_2, R.string.surv2_3, R.string.surv2_4, R.string.surv2_5, R.string.surv2_6 }, { R.string.surv3_1, R.string.surv3_2, R.string.surv3_3 } }; private static final int[][] mImageViews = { { R.drawable.surv_pioche, R.drawable.surv_crafting, R.drawable.surv_hache, R.drawable.surv_charbon, R.drawable.surv_torch, R.drawable.surv_abri }, { R.drawable.surv_malle, R.drawable.surv_four, R.drawable.surv_pelle, R.drawable.surv_repere, R.drawable.surv_sand, R.drawable.surv_glass }, { R.drawable.surv_1, R.drawable.surv_2, R.drawable.surv_3, R.drawable.surv_4, R.drawable.surv_5, R.drawable.surv_6, R.drawable.surv_7, R.drawable.surv_8 }, }; private static final int[] mNextButtons = { R.string.surv1_next, R.string.surv2_next, R.string.surv3_next }; @Override public void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); final Intent i = getIntent(); if (savedInstanceState != null && savedInstanceState.containsKey(KEY_LAYOUT_ID)) { mLayoutId = savedInstanceState.getInt(KEY_LAYOUT_ID, 0); } else if (i != null) { mLayoutId = i.getIntExtra(KEY_LAYOUT_ID, 0); } else { mLayoutId = 0; } // Layout //setContentView(mSurvivalLayouts[mLayoutId]); LinearLayout ll; ScrollView sv; TextView tv; ImageView iv; Button b; sv = new ScrollView(this); sv.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); ll = new LinearLayout(this); ll.setOrientation(LinearLayout.VERTICAL); ll.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); tv = new TextView(this); tv.setId(R.id.title); tv.setText(getString(mTitles[mLayoutId])); ll.addView(tv); for (final int textId: mTextViews[mLayoutId]) { tv = new TextView(this); tv.setText(getString(textId)); ll.addView(tv); } for (final int imgId: mImageViews[mLayoutId]) { L.i("Creating image: "+imgId); iv = new ImageView(this); iv.setImageResource(imgId); ll.addView(iv); } b = new Button(this); b.setText(getString(mNextButtons[mLayoutId])); b.setId(R.id.survival_next); ll.addView(b); sv.addView(ll); setContentView(sv); // Title Util.setTitleFont(this, findViewById(R.id.title)); // "Next" button final View nextButton = findViewById(R.id.survival_next); Util.setFont(this, nextButton, "Lobster.ttf"); nextButton.setOnClickListener(new OnClickListener() { @Override public void onClick(final View v) { final Intent next = new Intent(SurvivalActivity.this, SurvivalActivity.class); next.putExtra(KEY_LAYOUT_ID, (mLayoutId + 1) % mSurvivalLayouts.length); startActivity(next); finish(); } }); } </code></pre> As you can see I am just inflating the views directly, and <code>L.i</code> (which is an alias to <code>Log.i(TAG, ...)</code>) indicates what was the last ImageView inflated before any crash. I ran the app, saw the 1st activity, then the second, and as previously it crashes while loading the third one. The last ID I saw in the logcat was the last picture <code>R.drawable.surv_8</code>. This is a 630x377 jpeg file, 45 kiB. I tried to change the order of the views like this: <pre><code>private static final int[][] mImageViews = { { R.drawable.surv_pioche, R.drawable.surv_crafting, R.drawable.surv_hache, R.drawable.surv_charbon, R.drawable.surv_torch, R.drawable.surv_abri }, { R.drawable.surv_malle, R.drawable.surv_four, R.drawable.surv_pelle, R.drawable.surv_repere, R.drawable.surv_sand, R.drawable.surv_glass }, { R.drawable.surv_8, R.drawable.surv_1, R.drawable.surv_2, R.drawable.surv_3, R.drawable.surv_4, R.drawable.surv_5, R.drawable.surv_6, R.drawable.surv_7, }, }; </code></pre> So that surv_8 is first. The app is still crashing at the last picture, which is <code>R.drawable.surv_7</code>. So that is not an image issue. Then I removed one of the pictures out of <code>mImageViews[2]</code> so that I have only 7 pictures instead of 8. The app is working as expected: the activity loads, when I click the button I go to the next one, and on the last I go to the first. No crash. I can however tell that the activity 1 and 2 stay into memory. Indeed, have a look at the timings: <pre><code>03-04 15:47:13.685 I/ActivityManager(17430): Displayed net.bicou.myapp/.SurvivalActivity: +2s570ms 03-04 15:47:36.834 I/ActivityManager(17430): Displayed net.bicou.myapp/.SurvivalActivity: +803ms 03-04 15:47:39.756 I/ActivityManager(17430): Displayed net.bicou.myapp/.SurvivalActivity: +1s476ms 03-04 15:47:44.201 I/ActivityManager(17430): Displayed net.bicou.myapp/.SurvivalActivity: +462ms 03-04 15:47:46.717 I/ActivityManager(17430): Displayed net.bicou.myapp/.SurvivalActivity: +474ms 03-04 15:47:48.599 I/ActivityManager(17430): Displayed net.bicou.myapp/.SurvivalActivity: +474ms </code></pre> 400ms instead of 1.5-2.5 sec to load the activity. Why is this staying into memory? => ** Do I need to manually free all pictures upon <code>onDestroy()</code> ? ** => What do you think about this: <a href="http://androidactivity.wordpress.com/2011/09/24/solution-for-outofmemoryerror-bitmap-size-exceeds-vm-budget/" rel="nofollow">http://androidactivity.wordpress.com/2011/09/24/solution-for-outofmemoryerror-bitmap-size-exceeds-vm-budget/</a> With this solution I could load like 10 bitmaps globally, and I would free some while loading another activity?

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.
